[PMID: 39215882 DOI: 10.1007/s10384-024-01113-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Accepted: 07/25/2024] [Indexed: 09/04/2024]
Abstract
PURPOSE To compare the distance of the medial rectus muscle insertion to the limbus (DMIL) between patients with acute acquired comitant esotropia (AACE) associated with excessive digital device usage (EDDU) and exotropic patients. STUDY DESIGN Retrospective study. METHODS The medical records of 72 eyes of 44 patients with EDDU were retrospectively analyzed. The DMIL was measured from the anterior part at the midpoint of the medial rectus muscle insertion into the anterior limbus using a caliper after dissecting the medial rectus muscle with two control sutures at 12 o'clock and 6 o'clock. The DMIL in the non-fixation eye was compared between 44 patients with AACE and 23 patients with exotropia. RESULTS The mean daily EDDU was 6.5 ± 3.1 h. The mean cycloplegic refractive errors (spherical equivalent: SE) were - 3.18 ± 2.52 diopters (D) OD and - 3.03 ± 2.42 D OS. The mean DMIL in the 72 eyes of 44 patients with AACE associated with EDDU was 4.30 ± 0.66 mm. The difference in DMIL of non-fixation eyes between 44 AACE patients and 23 exotropic patients was significant (4.28 ± 0.65 mm vs. 5.28 ± 0.50 mm, p < 0.0001). However, the SE in 44 non-dominant eyes of AACE was - 3.08 ± 2.56 D, significantly stronger than - 1.22 ± 1.93 D in the 23 exotropic eyes (p = 0.008). CONCLUSION DMIL in patients with AACE associated with EDDU was significantly shorter. This anatomical anomaly may be an etiology of AACE associated with EDDU.

Abstract
Objective The aim of this study was to evaluate the impact of the COVID-19 pandemic on ocular health related to digital device usage among university students in Lebanon. Design A cross-sectional design was utilized to examine the association between the pandemic and ocular health. Participants A total of 255 university students in Lebanon participated in the study, selected based on their enrollment during the pandemic. Methods An online survey assessed participants' digital device usage, awareness of digital eye strain, and experienced symptoms. The study addressed the relationship between symptom frequency and screen time, especially in their connection to the pandemic and online learning. Results Prior to the pandemic, the majority of participants (73.0 %) were unaware of digital eye strain. Following the transition to online learning, nearly half of the participants (47.0 %) reported using digital devices for 12 or more hours. The majority (92.0 %) experienced a substantial increase in daily digital device usage for learning, with an average increase of 3-5 h. Symptoms of digital eye strain, including headache, burning of eyes, blurry vision, sensitivity to light, worsening of vision and dryness of the eyes intensified in both frequency and severity during the pandemic and online learning period. Conclusions The study emphasizes the importance of promoting healthy habits and implementing preventive measures to reduce the prevalence of digital eye strain symptoms among university students. Healthcare professionals and public health authorities should educate individuals on strategies to alleviate digital eye strain, considering the persistent reliance on digital devices beyond the pandemic.

Abstract
This research work focuses on evaluating the development of our three-step digitization approach, designed to transform traditional lectures into engaging digital learning experiences. Aimed at offering an easy-to-use solution for educators, this approach addresses the pressing challenges of modern educational environments by enhancing accessibility, engagement, and effectiveness of learning through digital means.Quantitative analysis demonstrated a notable increase in knowledge gain for students engaged with the digital format (t(230) = -2.795, p = 0.006) over traditional methods. Additionally, it was observed that the online setting significantly improved concentration levels (t(230) = -5.801, p < .001) and reduced distractions (t(230) = 2.848, p = 0.005). Emotional assessments, based on the Achievement Emotions Questionnaire (AEQ), indicated an elevation in enjoyment (t(230) = -4.717, p < .001) and a reduction in anxiety (t(230) = 9.446, p < .001) within the digital learning environment. A substantial preference for the digital course format was expressed by 61.0% of participants, with 71.4% acknowledging its superior efficiency compared to 14.3% for traditional lectures.Qualitative feedback underscored the digital format's flexibility, comprehensive learning experience, and immediate feedback as key benefits. Nevertheless, nuances such as a preferred understanding in face-to-face interactions and the absence of a social component in digital settings were noted.To conclude, the findings from this study illuminate the significant advantages of the three-step digitization approach in meeting contemporary educational challenges. By facilitating an enhanced knowledge acquisition and fostering a supportive emotional climate, this approach signifies a promising direction for the future of medical education and beyond, fusing the convenience of digital solutions with the depth and engagement of traditional learning methodologies.

Abstract
INTRODUCTION Habitual viewing behaviour is widely believed to be an important contributing factor to the onset and progression of myopia and may be task dependent. The purpose of this study was to quantify the habitual viewing distance of children performing five different tasks on a smartphone digital device. METHODS The real-time viewing distance in 38 children with their habitual correction was measured using software (MyopiaApp) on a handheld (Google Pixel 3) device. Five tasks were performed in a randomised sequence: playing a game, watching video in a light (680 lux) and dark (5.5 lux) environment and reading small (8 pt) and large (16 pt) text. ANCOVA statistical analysis was used to evaluate the effect of task, group (myope vs. non-myope) and arm length on the median relative viewing distance. RESULTS Arm length was not correlated with viewing distance in any of the tasks, and there was no significant difference in viewing distance between any of the tasks. Specifically, a two-way mixed ANCOVA indicated that task, refractive group (myopic vs. non-myopic), age and arm length, as well as all two-way interactions were not significantly associated with viewing distance. Overall, 60% of the total variance in viewing distance was accounted for by individual differences. CONCLUSIONS The average handheld viewing distance was similar across a variety of everyday tasks in a representative sample of myopic and emmetropic children. Neither arm length, age nor refractive group were associated with viewing distance in any of the tasks. Importantly, myopic children of a given size did not hold the smartphone digital device at a different distance for any task than their equally sized non-myopic peers. However, both groups exhibited high inter-individual variability in mean viewing distance, indicating some subjects performed all tasks at further distances while other subjects used at nearer distances.

Abstract
Background and aims Increased use of digital devices in the modern era has led to the development of digital eye strain (DES) or computer vision syndrome in their users. This can result in the development of various ocular and visual symptoms among them. In this study, the authors aimed to view the prevalence of digital eye strain among radiology physicians in Pakistan and their associated risk factors. Materials and methods A cross-sectional study was conducted to evaluate occupational DES among radiology physicians in Pakistan. The data collection was done using the convenience sampling technique, and the data were analyzed using IBM SPSS for Windows, Version 25.0. Results Out of the 247 respondents, 33.6% were males and 66.4% were females. 41.7% of them were between 30 and 40 years of age and 51.8% of them were radiology residents. 52.2% of the participants had a refractive error and were using a corrective lens. The majority of the radiologists in our study (84.2%) preferred picture archiving and communication system (PACS) over films and 82.2% of them reported having breaks of less than 15 min. Major symptoms reported by the participants were tired or heavy eyes (69.6%) and headache (69.3%). The proportion of developing DES was higher in females [P=0.001, adjusted odds ratio (aOR)=2.94], radiology residents (P=0.031, aOR=3.29), and working hours of more than 4 h per day (P<0.001, aOR=0.04). Conclusion With recent advances in the field of radiology in Pakistan, the frequency of developing DES among radiologists is increasing. Being a female, having long working hours, and having noticeable flickers on the digital screens were among the significant factors in developing DES among radiologists.

Abstract
INTRODUCTION Supplementation with dietary neuro-pigments lutein (L) and zeaxanthin (Z) has been shown to improve many aspects of visual and cognitive function in adults. In this study, we tested whether a similar intervention could improve such outcomes in preadolescent children. METHODS Sixty children (age range 5-12 years) were randomized in a 2:1 ratio in this double-blind, placebo-controlled clinical trial. Subjects were supplemented with gummies containing either a combination of 10 mg lutein and 2 mg zeaxanthin (LZ) or placebo for 180 days. Macular pigment optical density (MPOD) was the primary endpoint. The secondary endpoints included serum levels of L and Z, and brain-derived neurotrophic factor (BDNF), critical flicker fusion (CFF), eye strain and fatigue using visual analogue scales (VAS), Children's Sleep Habits Questionnaire-Abbreviated (CSHQ-A), and Creyos Health cognitive domains like attention, focus/concentration, episodic memory and learning, visuospatial working memory, and visuospatial processing speed. Safety was assessed throughout the study on the basis of physical examination, vital signs, clinical laboratory tests, and monitoring of adverse events. RESULTS The LZ group showed significant increases in MPOD at all visits post-supplementation, with significant increases as early as day 42 compared to placebo. The LZ group showed significant increases in serum lutein levels, reduced eye strain and fatigue, and improved cognitive performance (focus, episodic memory and learning, visuospatial working memory) at days 90 and 180 compared to placebo. Further, the LZ group showed significant increases in processing speed (CFF), attention, visuospatial processing, and serum Z and BDNF levels on day 180 compared to placebo. No safety concerns were observed. CONCLUSIONS Supplementing LZ resulted in increased MPOD levels, along with increased serum levels of L, Z, and BDNF. These changes were associated with improved visual and cognitive performances and reduction in eye strain and eye fatigue in the children receiving LZ gummies. The investigational product was safe and well tolerated. TRIAL REGISTRATION http://ctri.nic.in/ Identifier CTRI/2022/05/042364.

Abstract
OBJECTIVES This study aimed to assess the impact of COVID-19-related school closures on screen time and video gaming habits among governmental school students in Qatar and explore the prevalence of Internet Gaming Disorder (IGD) within this context. METHODS A cross-sectional approach was employed, spanning two months from June to August 2022. A random sample of students aged 8-15 years was drawn from the national electronic health record system of Qatar. Telephone interviews with parents were conducted to collect data. The Parental Internet Gaming Disorder Scale (PIGDS) was used for IGD assessment. RESULTS Of 428 parents, 257 (60%) confirmed their child's engagement in video gaming during school closures. Participants averaged 11 years in age with 92 (35.8%) females and 165 (64.2%) males. Nationality included 62.6% expatriates and 37.4% Qatari locals. Average weekly screen time increased significantly from 19.7 ± 10.1 h to 31.9 ± 12.6 h during closure (p < 0.001). Video gaming time rose from 8.6 ± 8.6 h to 13.0 ± 12.4 h per week (p < 0.001). The prevalence of IGD was 8.6% (95% CI 5.4-12.7). Male students, expatriates, and those reporting increased video gaming time were more likely to develop IGD than their female and local counterparts. CONCLUSION The observed associations between video gaming increase and IGD highlight the need for focused interventions to address potential risks and promote healthier digital habits among this population.

Abstract
BACKGROUND Computer vision syndrome has become a significant public health problem, especially in developing countries. Therefore, this study aims to identify the prevalence of computer vision syndrome during the COVID-19 pandemic. METHODS A systematic review and meta-analysis of the literature was conducted using the databases PubMed, Scopus, Web of Science, and Embase up to February 22, 2023, using the search terms "Computer Vision Syndrome" and "COVID-19". Three authors independently performed study selection, quality assessment, and data extraction, and the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument was used to evaluate study quality. Heterogeneity was assessed using the statistical test I2, and the R version 4.2.3 program was used for statistical analysis. RESULTS A total of 192 studies were retrieved, of which 18 were included in the final meta-analysis. The total sample included 10,337 participants from 12 countries. The combined prevalence of computer vision syndrome was 74% (95% CI: 66, 81). Subgroup analysis based on country revealed a higher prevalence of computer vision syndrome in Pakistan (99%, 95% CI: 97, 100) and a lower prevalence in Turkey (48%, 95% CI: 44, 52). In addition, subgroup analysis based on study subjects showed a prevalence of 82% (95% CI: 74, 89) for computer vision syndrome in non-students and 70% (95% CI: 60, 80) among students. CONCLUSION According to the study, 74% of the participants experienced computer vision syndrome during the COVID-19 pandemic. Given this finding, it is essential to implement preventive and therapeutic measures to reduce the risk of developing computer vision syndrome and improve the quality of life of those affected. TRIAL REGISTRATION The protocol for this systematic review and meta-analysis was registered in the international registry of systematic reviews, the International Prospective Register of Systematic Reviews (PROSPERO), with registration number CRD42022345965.

Abstract
OBJECTIVE The aim of this study was to summarize the evidence regarding screen use as a contributing factor in pediatric headache and migraine. BACKGROUND Screen exposure is often reported as a headache trigger, though there is no current consensus in terms of how screen type, duration, or frequency influences pediatric headache and the associated burden of disease. METHODS A systematic search in PubMed, Scopus, Cochrane Library, ProQuest Health and Medical Database, and Google Scholar was performed through November 2022 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. All English-language articles of pediatric patients aged ≤18 years evaluating screen use in relation to headache were included. RESULTS A total of 48 studies were included. Nearly all studies were cross-sectional and represented international samples. The strongest association between screen use and headache found was for duration of use, and computer use emerged as the most common device type related to headache. While there were mixed findings related to screen use and specific headache diagnosis, migraine appeared to confer a higher risk. Across studies, there were insufficient data to assess the impact of screen use on headache frequency or headache-related disability. Several studies demonstrated changes in screen use and headache patterns related to the COVID-19 pandemic and computer vision syndrome was commonly reported. CONCLUSIONS While there is preliminary evidence supporting possible associations between screen use and pediatric headache, there are several limitations in the present review including a lack of prospective and randomized controlled trials to better demonstrate causal relationships as well as methodological limitations with significant variability in how both headache and screen use are defined and measured. Future studies including real-time screen use and device monitoring are needed to better understand the influence of screen use behaviors on pediatric headache and to help further define best-use guidelines around these technologies.

Abstract
PURPOSE To determine how vision correction habits changed after the 2019 coronavirus disease (COVID-19) pandemic onset. METHODS Participants reported vision correction habits, refractive error, screen time, mask wearing time, and dry eye symptoms since the COVID-19 pandemic onset through email survey. RESULTS A total of 133 participants completed the survey. Worsening dry eye symptoms were associated with increased screen time ( P =0.04). Hours per day of spectacle wear increased by approximately 1 hr ( P =0.001) and was associated with increased screen time ( P =0.002). Worsening dry eye symptoms were associated with increased days per week of spectacle wear ( P =0.02). Participants wore contact lenses about one day per week less than before the pandemic ( P =0.0001). Increased mask wearing time was associated with increased days per week of contact lens wear ( P =0.03). CONCLUSIONS After pandemic onset, hours per day of spectacle wear increased, and days per week of contact lens wear decreased. Increases in hourly spectacle wear were associated with increased screen time, whereas increased daily contact lens wear was associated with increased mask wear time, suggesting that spectacles may be preferred for screen time activities and contact lenses for mask wear.

[PMID: 38070708 DOI: 10.1016/j.jtos.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 12/01/2023] [Accepted: 12/04/2023] [Indexed: 12/18/2023]
Abstract
Dry eye disease (DED), a multifactorial ocular disease that significantly impacts quality of life, is most commonly reported in adults. This review describes the prevalence, risk factors, diagnosis and management of DED in children. A literature search, conducted from January 2000-December 2022, identified 54 relevant publications. Using similar diagnostic criteria to those reported in adults, namely standardized questionnaires and evaluation of tear film homeostatic signs, the prevalence of DED in children ranged from 5.5% to 23.1 %. There was limited evidence for the influence of ethnicity in children, however some studies reported an effect of sex in older children. Factors independently associated with DED included digital device use, duration of digital device use, outdoor time and urban living, Rates of DED were higher in children with ocular allergy and underlying systemic diseases. Compared with similar studies in adults, the prevalence of a prior DED diagnosis or a diagnosis based on signs and symptoms was lower in children, but symptoms were commonly reported. Treatment options were similar to those in adults, including lifestyle modifications, blinking, management of lid disease and unpreserved lubricants in mild disease with escalating treatment with severity. Management requires careful exploration of symptoms, medical history and the diagnosis and management of ocular comorbidities such as allergy and anterior blepharitis. Appropriately powered population-based studies are required to understand the prevalence of and risk factors for DED in children. Development of age-appropriate thresholds for signs and symptoms of DED would support better diagnosis of disease and understanding of natural history.

Abstract
BACKGROUND Ever since the start of the coronavirus disease 2019 (COVID-19) pandemic, students have been spending an increasingly longer time staring at electrical devices to take online courses. OBJECTIVE This study aimed to investigate the effect of the virtual class environment on eye and musculoskeletal problems in university students during the COVID-19 pandemic. METHODS A total of 365 university students were enrolled in this study. They completed an online survey to examine the effects of online learning on eye and musculoskeletal health during the COVID-19 pandemic. The questionnaires consisted of four sections: demographic and general information, environmental and work factors, device-related factors, and visual display terminal syndrome (VDTS). RESULTS Participants have been taking online classes of 14.5 hours per week during the COVID-19 pandemic. They reported the mean daily usage of digital devices of 4.8±2.2 hours before the pandemic but this increased to 8.1±2.9 during the pandemic. Eye fatigue and neck, shoulder, and back pain have also been reported. The mean VDTS score was significantly influenced by gender, obesity, daily exercise, regular breaks, wear of blue light-blocking glasses, daily hours of electronic device use, and illumination of room. CONCLUSION The results of this study showed that university students taking online classes suffered more from VDTS, especially in eye fatigue and neck, lower back, and shoulder pain during COVID-19 pandemic than prior. This study suggests that it is necessary to take breaks in online classes and regularly provide appropriate eye exercise and physical activity to prevent VDTS.

Abstract
PURPOSE This review aimed to estimate the prevalence of computer vision syndrome (CVS) in the general population and subgroups. METHODS A search was conducted in the following the databases: PubMed, SCOPUS, EMBASE, and Web of Science until February 13, 2023. We included studies that assessed the prevalence of CVS in any population. The Joanna Briggs Institute's critical appraisal tool was used to evaluate the methodological quality. A meta-analysis of the prevalence of CVS was done using a random-effects model, assessing the sources of heterogeneity using subgroup and meta-regression analyses. RESULTS A total of 103 cross-sectional studies with 66 577 participants were included. The prevalence of CVS was 69.0% (95% CI: 62.3 to 75.3; I2: 99.7%), ranging from 12.1 to 97.3% across studies. Point prevalence was higher in women than in men (71.4 vs. 61.8%), university students (76.1%), Africa (71.2%), Asia (69.9%), contact lens wearers (73.1% vs. 63.8%) in studies conducted before the COVID-19 pandemic (72.8%), and in those that did not use the CVS-Q questionnaire (75.4%). In meta-regression, using the CVS-Q scale was associated with a lower prevalence of CVS. CONCLUSION Seven out of ten people suffer from CVS. Preventive strategies and interventions are needed to decrease the prevalence of this condition which can affect productivity and quality of life. Future studies should standardize a definition of CVS.

Abstract
When the eyes work intensively, it is easy to have eye discomfort such as blurred vision, soreness, dryness, and tearing, that is, visual fatigue. Visual fatigue not only affects work and study efficiency, but long-term visual fatigue can also easily affect physical and mental health. In recent years, with the popularization of electronic products, although it has brought convenience to the office and study, it has also caused more frequent visual fatigue among people who use electronic devices. Moreover, studies have reported that the number of people with visual fatigue is showing a trend of increasing year by year. The range of people involved is also extensive, especially students, people who have been engaged in computer work and fine instruments (such as microscopes) for a long time, and older adults with aging eye function. More and more studies have proposed that supplementation with the proper nutrients can effectively relieve visual fatigue and promote eye health. This review discusses the physiological mechanisms of visual fatigue and the design ideas of animal experiments from the perspective of modern nutritional science. Functional food ingredients with the ability to alleviate visual fatigue are discussed in detail.

Abstract
OBJECTIVE During the COVID-19 pandemic, many people devoted longer time to screen viewing due to the need for study, work, and online social activities, instead of outdoor activities, which may have led to an increase in dry eye symptoms. This study aimed to evaluate the prevalence of dry eye during the COVID-19 pandemic. METHODS PubMed, Cochrane Library, Embase, and Web of Science were searched from January 1, 2020 to October 20, 2022. Cross-sectional surveys on dry eye prevalence conducted after January 1, 2020 were included. Two review authors independently performed data extraction and assessed study quality. The random-effects model was used to analyze the prevalence of dry eye, and the odds ratio was used to assess the strength of the association between variables. Subgroup analysis was performed to detect heterogeneity, the leave-one-out method for sensitivity analysis, and the Egger test for publication bias. RESULTS A total of eleven studies with 15692 individuals met the eligibility criteria. The prevalence of dry eye during the COVID-19 pandemic was 61.0% (95%CI: 51.8%-70.2%) globally and 56.7% (95%CI: 45.3%-68.1%) in Asia. The prevalence of dry eye had significant differences in sex and visual display time, with higher prevalence among females and visual display time of more than 4 hours per day. Subgroup analysis was performed based on diagnostic tools, study population, and average age. A significant difference was found in diagnostic tools, but no significant change in heterogeneity (P<0.05). The leave-one-out method showed stable results, and the Egger test identified no significant publication bias. CONCLUSION The prevalence of dry eye during the COVID-19 pandemic is significantly higher than before, and a higher prevalence is found among females and those having a visual display time of more than 4 hours per day.

Abstract
PURPOSE To assess clinical features, visual outcomes, and setting of mobile battery blast-induced eye injuries in children. METHODS Retrospective case sheets of children with mobile battery blast injuries were reviewed at a tertiary eye care center from January 2015 to March 2022. We noted the mode of injury, battery status, and clinical presentation and analyzed the treatment outcomes. RESULTS The study included 14 eyes of 11 patients. Three patients (27%) had bilateral ocular injuries. The most common reasons for the blast were wiring a bulb to the battery or charging the battery with a universal mobile charger, seen in four cases each. Three eyes had closed-globe injuries (CGIs), whereas 11 had open-globe injuries (OGIs). Of the 11 eyes with OGI, four also had a retained intraocular foreign body (IOFB). Only four (36%) eyes having OGI could achieve vision better than 6/60. All three eyes with CGIs developed secondary glaucoma, and two underwent trabeculectomy. However, the visual prognosis was better (>6/36) in eyes with CGI. Overall, mean visual acuity at the final follow-up was improved to 1.41 ± 1.14 logMAR from 2.32 ± 0.76 logMAR at presentation. This was also found to be statistically significant with a P value of 0.02. CONCLUSION Battery blast-induced ocular injuries, although rare, often lead to poor outcomes. Apart from charging, playing with discarded or damaged batteries was a common reason for battery blasts in our series.

Abstract
Aim This study aimed to assess the prevalence of Computer Vision Syndrome (CVS) among children and adolescents in Qatar during the period of remote learning and explore the associated factors and discuss some digital health remedies that might reduce the risk. Methods We conducted an analytical cross-sectional study between June and August 2022 by collecting data via telephone interviews with parents of selected students utilizing the Computer Vision Syndrome Questionnaire (CVS-Q). Results We completed 1,546 interviews. The mean age of the students was (11 ± 2), male: female ratio was almost 1:1. About one quarter (368, 23.8%) of parents reported a previous diagnosis of visual disturbances among their children with over 88% of them wearing eyeglasses or medical contact lenses. The prevalence of CVS in our sample was about 8% (95%CI: 6.8-9.6). Mother's employment, having positive history of visual disturbances, and excess screen time were found to be significant predictors of CVS. Conclusion Health care providers in collaboration with teachers should provide parents with evidence-based strategies to prevent or minimize the digital eye strain among students. In the landscape of remote learning, the implementation of digital remedies emerges as a proactive approach to mitigate the risk of digital eye strain.

Abstract
PURPOSE The purpose of this cohort study was to investigate the association between the prevalence of abnormal ocular examination results and the common visual symptoms of eye strain, blurred vision and photophobia. METHODS Consecutive first-visit outpatients with best-corrected visual acuity better than 20/30 in both eyes were enrolled and those with a history of intra-ocular lens implantation and glaucoma were excluded. Dry eye-related examinations and retinal thickness measurement were conducted. The odds ratio (OR) was calculated with logistic regression analyses of ocular data in relation to the presence of visual symptoms. RESULTS A total of 6078 patients (3920 women, mean age 49.0 ± 20.4 years) were analyzed. The prevalence of each symptom was 31.8% for eye strain, 22.5% for blurred vision and 16.0% for photophobia. A significant risk factor for eye strain was short tear break-up time (TBUT) (OR 1.88), superficial punctate keratitis (SPK) (OR 1.44), and thickness of ganglion cell complex (GCC) (OR 1.30). Risk factors for blurred vision were short TBUT (OR 1.85), SPK (OR 1.24) and GCC (OR 0.59). Risk factors for photophobia were short TBUT (OR 1.77) and SPK (OR 1.32). Schirmer test value, peripapillary nerve fiber layer thickness and full macular thickness were not associated with the tested symptoms. CONCLUSION The current study successfully identified female gender, short TBUT, and SPK as significant risk factors for eye strain, blurred vision, and photophobia with considerable ORs.

Abstract
The COVID-19 pandemic came with many new challenges that forced personal and professional lifestyle modifications. Medical facilities were in scarcity against this new unknown enemy and were challenged with the overloaded patient flow, scarcity of healthcare staff, and evolving treatment modalities with a better understanding of the virus each day. Ophthalmology as a "branch of medicine" suffered challenges initially because of a lack of guidelines for patient management, close working distance during routine examinations, and halt of major surgeries, including cataracts. Pediatric ophthalmology had major implications, as reduced outpatient visits would mean deeper amblyopia, and changed lifestyles, including online classes and home refinement, predisposing children to myopia, digital eye strain, and worsening of strabismus. COVID-19 also unveiled underlying accommodation and convergence anomalies that predisposed pediatric and adolescent patients to an increased prevalence of headache and acute onset esotropia. Teleophthalmology and other innovative solutions, including the use of prism glasses, safe slit-lamp shields, alternative ways of school screening with the use of photoscreeners, performing retinoscopy only when needed, and using autorefractors were among the few guidelines or modifications adopted which helped in the efficient and safe management of pediatric patients. Many pediatric ophthalmologists also suffered in terms of financial constraints due to loss of salary or even closure of private practices. School screening and retinopathy of prematurity screening suffered a great setback and costed a lot of vision years, data of which remains under-reported. Important implications and learnings from the pandemic to mitigate future similar situations include using teleophthalmology and virtual platforms for the triage of patients, managing non-emergency conditions without physical consultations, and utilizing home-based vision assessment techniques customized for different age groups. Though this pandemic had a lot of negative implications, the innovations, modifications, and other important learnings helped pediatric ophthalmologists in navigating safely.

Abstract
The global proliferation of video games, particularly among children, has led to growing concerns about the potential impact on children's social development. Executive function is a cognitive ability that plays a crucial role in children's social development, but a child's age constrains its development. To examine the association between video game engagement and children's social development while considering the mediating role of executive function and the moderating role of age, a questionnaire was distributed to a sample of 431 parents. The results revealed a negative relation between video game engagement and social development in children, with executive function found to mediate this relation fully. Additionally, the negative association between video game engagement and executive function became more pronounced as children grew older. In light of these findings, it is advisable to adopt proactive strategies to limit excessive video game use, consider the developmental characteristics of children at different ages, and prioritize the promotion of executive function to facilitate social development among children.

Abstract
Background Digital eye strain has become a serious concern due to the exponential increase in the usage of digital devices in recent years. This study aimed to assess the prevalence of digital eye strain among medical students. Methods A cross-sectional study was conducted over a period of one month, from 15th June to 15th July 2023, among undergraduate medical students at King Khalid University, Aseer Region, Saudi Arabia. An online survey was carried out using a structured questionnaire that was circulated through social media platforms (Facebook, Messenger, Instagram, Telegram, and WhatsApp). Results A total of 300 students were enrolled in this study. The prevalence of ocular problems, in descending order, was as follows: asthenopia had the highest prevalence at 30.5% (94), followed by conjunctivitis at 9.4% (29); squint, glaucoma, and cataract had lower prevalence rates of 3.9% (12), 1.6% (5), and 1.6% (5), respectively. The majority of participants used digital devices for fun (92.9% (286)) and study (95.5% (294)). Significant positive correlations were found between asthenopia and the hours spent on digital devices for studying (r = 0.161, p = 0.005), communication (r = 0.146, p = 0.011), and entertainment (r = 0.206, p < 0.001). Conclusions A substantial number of medical students are experiencing asthenopia. Prolonged usage of these devices is linked to a higher prevalence of asthenopia.

Abstract
Objective This study examined the prevalence of musculoskeletal disorders (MSDs) and their associated factors among 1st to 4th-year students at Walailak University who attended virtual classrooms for 1 week, 1 month, and 3 months. Method A cross-sectional study was conducted among 382 students aged 18-23 years with no history of musculoskeletal disease or psychiatric disorder who had at least three months of virtual classroom learning. Statistical analysis was performed using chi-squared and Fisher's exact tests. Results Most musculoskeletal abnormalities occurred in the shoulders, head and neck, and lower back at 1 week, 1 month, and 3 months, respectively. At one week and one month in virtual classrooms, the occurrence of MSDs among the students was correlated with psychosocial factors (p < 0.05), and at three months, MSDs were associated with personal factors such as body mass index and psychosocial factors (p < 0.05). Conclusion Stress management for students should be implemented in virtual classrooms to prevent MSDs.

Cross-Sectional Analyses of Factors Related to Digital Eye Strain Symptoms Among Children Using Online Learning Devices During the COVID-19 Pandemic in Thailand. Clin Ophthalmol 2023; 17:1769-1776. [PMID: 37366516 PMCID: PMC10290846 DOI: 10.2147/opth.s416877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 06/13/2023] [Indexed: 06/28/2023] Open
Abstract
Purpose Globally, the COVID-19 pandemic has influenced academic studies. Since 2019, most schools in Thailand have implemented online learning. Thus, several students are experiencing eye problems, including stinging, blurred vision, and epiphora. This study investigated the prevalence, eye symptoms, and characteristics associated with digital eye strain (DES) in children using digital devices. Patients and Methods In this cross-sectional study, a self-administered electronic questionnaire via google forms was used to collect demographic data, digital device information, and DES characteristic information in children of age 8-18 years using online digital devices. The data collection was conducted between December 2021 and January 2022. Moreover, multivariable logistic regression analysis was performed to evaluate the potential characteristics associated with DES in children. Results From a total of 844 parents, 782 parents completed the questionnaire. The mean age of the children was 12.42 ± 2.82 years (8-18 years). During the pandemic, the most common duration of using digital devices was >8 hours (39.90%), compared to only 2-4 hours (36.70%) before. The prevalence of DES was 42.2% (330/782), divided into mild (29.8%), moderate (8.1%), and severe (4.3%) symptoms. The most common symptoms of DES included: a burning sensation in the eyes (55.24%), fear of worsening eyesight (53.07%), and excessive blinking of eyes (48.33%). The associated characteristics with DES were advanced age (OR=1.21, P<0.001), refractive error with (OR=2.04, P=0.004) and without (OR=6.11, P<0.001) correction, and unknown refractive error (OR=2.85, P<0.001). Conclusion The use of digital devices are inevitable; therefore, regulating the duration of study and entertainment using digital devices, especially in older ages, and correcting refractive error in children, is necessary to ameliorate DES.

Abstract
Introduction The prolonged use of digital devices is a major risk factor for digital eye strain (DES) syndrome. Aim To estimate the prevalence of DES symptoms among students at Imam Abdulrahman University who use digital devices for virtual learning and leisure activities. Methods This was a retrospective cross-sectional study conducted by asking medical students of Imam Abdulrahman bin Faisal University to complete a self-administered online questionnaire. The questionnaire was used to determine the effect of the hours spent on digital devices and other factors, such as screen distance and not using artificial tears, on the development of DES. The severity (moderate or severe) and frequency (occasionally, always, or never) of 16 eye strain-related symptoms, including eye pain, headache, and itching, were evaluated by using the Computer Vision Syndrome Questionnaire. Results The overall prevalence of DES in the sample was found to be 68.53%. The largest proportion of students were found to have mild DES (43.20%), and only 11% had severe DES. The most common symptoms reported in our sample were headache, dryness, and burning. Female gender, using smartphones for online classes, and not using eye lubricants were significantly associated with increased severity of DES. Conclusion In the wake of the COVID-19 pandemic, virtual learning has become an integral part of education, leading to increased use of digital technology. The aim of this study was to investigate the impact of virtual learning on eye strain and to determine the prevalence and effects of DES. A questionnaire was administered to participants, and the findings revealed a DES prevalence of 68.53%. The use of eye drops for lubrication and smartphones for classes was significantly associated with DES. Furthermore, females were found to be more susceptible to severe DES symptoms than males. The development of a tool such as the Computer Vision Syndrome Questionnaire to predict DES prevalence could reduce clinic time and resources by minimizing unnecessary follow-up and ophthalmology referrals.

Abstract
Purpose The present work style and lifestyle have increased the digital device use. Therefore, an increase in digital eyestrain is to be expected. We undertook a survey during coronavirus disease 2019 (COVID-19) pandemic to investigate the practice of 20/20/20 rule and its association with digital device use and asthenopic symptoms. While this rule is commonly advised, little is known about its validity. Methods An online survey form was disseminated through social media and emails. The questions for eye-related symptoms were similar to the convergence insufficiency symptom survey (CISS). Participants with age ≥5 years were included, with parents completing the survey for children (≤16 years). Results A total of 432 participants (mean ± standard deviation [SD]: 26.06 ± 13.92 years) were enrolled, of which 125 responses were for children. The 20/20/20 rule was practiced only by 34% of the participants either regularly (n = 38) or occasionally (n = 109). Those who had complaints of burning sensation and headache tended to practice this rule. Among adult participants, more females (47%) practiced this rule when compared to males (23%). Also, adult females significantly (P = 0.04) had more symptoms score when compared to males. In children, no such gender difference was found. Conclusion Only one-third of participants practice the 20/20/20 rule at least occasionally. More number of adult females being symptomatic and practicing in greater number could be due to higher prevalence of dry eye condition in females. While the symptom of burning sensation could be related to dry eye, that of headache could be related to refractive error or binocular vision dysfunctions.

Abstract
PURPOSE To evaluate the prevalence of computer vision syndrome (CVS)-related symptoms in a presbyopic population using the computer as the main work tool, as well as the relationship of CVS with the electronic device use habits and the ergonomic factors. METHODS A sample of 198 presbyopic participants (aged 45-65 years) who regularly work with a computer completed a customised questionnaire divided into: general demographics, optical correction commonly used and for work, habits of electronic devices use, ergonomic conditions during the working hours and CVS-related symptoms during work performance. A total of 10 CVS-related symptoms were questioned indicating the severity with which they occurred (0-4) and the median total symptom score (MTSS) was calculated as the sum of the symptoms. RESULTS The MTSS in this presbyopic population is 7 ± 5 symptoms. The most common symptoms reported by participants are dry eyes, tired eyes and difficulties in refocusing. MTSS is higher in women (p < 0.05), in laptop computer users (p < 0.05) and in teleworkers compared to office workers (p < 0.05). Regarding ergonomic conditions, MTSS is higher in participants who do not take breaks while working (p < 0.05), who have an inadequately lighting in the workspace (p < 0.05) and in the participants reporting neck (p < 0.01) or back pain (p < 0.001). CONCLUSION There is a relationship between CVS-related symptoms, the use of electronic devices and the ergonomic factors, which indicates the importance of adapting workplaces, especially for home-based teleworkers, and following basic visual ergonomics rules.

Abstract
BACKGROUND Adolescence is a formative period of social development. Adolescents have experienced considerable changes in their lives due to the COVID-19 pandemic. We conducted a longitudinal study to examine the effects of the COVID-19 pandemic on adolescents' prosocial attributes and empathy, as well as their longitudinal bilateral relationships. METHODS A total of 2,510 students from five junior schools in Sichuan Province were recruited via random cluster sampling. Data were collected in December 2019 (Wave 1, before the outbreak of the pandemic) and July 2020 (Wave 2, during the pandemic) in Chengdu, Sichuan, China. Prosocial attributes and empathy were measured with the Positive Youth Development Scale (GPYDS) subscale and Chinese Empathy Scale, respectively. RESULTS During the pandemic, both empathy and prosocial attributes decreased significantly from 49.89 (9.12) and 49.89 (8.80) before to 48.29 (8.72) and 49.39 (9.26) (p < 0.001), respectively. A higher level of empathy at Wave 1 significantly predicted higher prosocial attributes at Wave 2 (β = 0.173, SE = 0.021, t = 8.430, p < 0.001). A lower prosocial attributes score predicted a significantly lower empathy score from Wave 1 to Wave 2 (β = 0.100, SE = 0.021, t = 4,884, p < 0.001). CONCLUSIONS The COVID-19 pandemic has had detrimental effects on adolescents' empathy and prosocial attributes. Special attention should be given to these two longitudinally associated factors in any social crisis, such as the COVID-19 pandemic, considering their importance for adolescents' physical, mental, and social development.

Abstract
Aim/background Digital eye strain, also called computer vision syndrome (CVS), is a group of symptoms resulting from prolonged computer, tablet, e-reader, and cell phone use. The level of discomfort and the severity of these symptoms appear to increase with the amount of digital screen use. These symptoms include eyestrain, headaches, blurred vision, and dry eyes. This study aims to assess the changes in the prevalence of digital eye strain among college students in Riyadh, Saudi Arabia. Methods A cross-sectional study was conducted among university students at different college institutions in Riyadh, Saudi Arabia. Subjects were interviewed, and the data were collected using an online questionnaire. The questionnaire was composed of student demographic data, students' general knowledge and risk perception of digital eye strain, and the assessment of CVS symptoms questionnaire. Results Of the 364 university students, 55.5% were females, and 96.2% were aged between 18 and 29 years. A significant proportion of university students (84.6%) were using digital devices for five hours or more. The proportion of university students who were aware of the 20-20-20 rule was 37.4%. The overall prevalence of positive for CVS symptoms was 76.1%. Independent risk factors for CVS symptoms were gender female, ocular disorders, and using digital devices at a shorter distance. Conclusion There was a high prevalence of CVS symptoms among university students in our region. Female students with an ocular disease were more likely to exhibit CVS symptoms than other university students, but using a digital device at a longer distance could alleviate the symptoms of CVS. A longitudinal study is needed to establish the effect of CVS symptoms among university students, especially during the post-pandemic era.

Abstract
Eye strain when performing tasks reliant on a digital environment can cause discomfort, affecting productivity and quality of life. Digital eye strain (the preferred terminology) was defined as "the development or exacerbation of recurrent ocular symptoms and/or signs related specifically to digital device screen viewing". Digital eye strain prevalence of up to 97% has been reported, due to no previously agreed definition/diagnostic criteria and limitations of current questionnaires which fail to differentiate such symptoms from those arising from non-digital tasks. Objective signs such as blink rate or critical flicker frequency changes are not 'diagnostic' of digital eye strain nor validated as sensitive. The mechanisms attributed to ocular surface disease exacerbation are mainly reduced blink rate and completeness, partial/uncorrected refractive error and/or underlying binocular vision anomalies, together with the cognitive demand of the task and differences in position, size, brightness and glare compared to an equivalent non-digital task. In general, interventions are not well established; patients experiencing digital eye strain should be provided with a full refractive correction for the appropriate working distances. Improving blinking, optimizing the work environment and encouraging regular breaks may help. Based on current, best evidence, blue-light blocking interventions do not appear to be an effective management strategy. More and larger clinical trials are needed to assess artificial tear effectiveness for relieving digital eye strain, particularly comparing different constituents; a systematic review within the report identified use of secretagogues and warm compress/humidity goggles/ambient humidifiers as promising strategies, along with nutritional supplementation (such as omega-3 fatty acid supplementation and berry extracts).

Abstract
Prolonged electronic screen use can cause digital eye strain. It can be difficult to rectify due to increasing smartphone reliance, potentially leading to serious public health problems. To investigate the association between time spent on smartphones and digital eye strain (DES) among Hong Kong Chinese school-aged children. Of a total of 1,508 students (748 males, 49.6%) from 8 to 14 years old (mean age = 10.91 years, SD = 2.01) who provided valid data on DES, the 1,298 (86%) who completed the DES questionnaire at 1-year follow-up were included in the analysis. DES was measured using a 10-item scale, and the sum of the 10 dichotomised scores was used as the DES total score. The most commonly reported symptoms were eye fatigue (n = 804, 53.3%), blurred vision (changing from reading to distance viewing) (n = 586, 38.9%), and irritated or burning eyes (n = 516, 34.2%). The DES total scores at baseline and 1-year follow-up were 2.91 (SD = 2.90) and 3.20 (SD = 3.19), respectively. Linear regression controlling for demographic and socio-economic confounders showed that participants with baseline smartphone usage of 241 + min/d had a significantly higher baseline total DES score than those with baseline smartphone usage of 0-60 min/d (2.44 vs 3.21, P < 0.001), and participants with baseline smartphone usage of 181-240 min/d had a significantly higher 1-year follow-up total DES score than those with baseline smartphone usage of 0-60 min/d (2.80 vs 3.50, P = 0.003).

Abstract
The coronavirus disease 2019 (COVID-19) pandemic that has been going on since the beginning of 2020 has forced governments to take a policy to implement online learning. This policy is an effort to break the chain of virus spread in education clusters. For schools and universities that are not used to carrying out online learning, this condition is a problem. Therefore, measurement is needed to ensure effectiveness. In this study, the effectiveness was measured using the variables specified in the Indonesian Online Learning System (Sistem Pembelajaran Daring (SPADA)) 2019 set by the Indonesian government. Data collection was carried out by quantitative and qualitative methods. Quantitative analysis was carried out through questionnaires administered to students while qualitative was carried out by interviewing students and lecturers. The data were processed using cross-tabulation analysis and multiple linear regression. Strengths, Weaknesses, Opportunities, and Challenges were analyzed to assess online learning. As research results, it is found that online learning is quite effective, but there are still many things that can be improved to increase the effectiveness of online learning.

Abstract
Digital Eye Strain (DES) is a clinical syndrome manifested with visual disturbances and/or ophthalmic dysfunction related to the usage of screen-enabled digital equipment. This term is gradually replacing the older term computer vision syndrome (CVS) that focused on the same symptoms found on personal computer users. DES is encountered more frequently during the past years due to the explosive increase in the usage of digital devices and subsequent increase in time in front of any screens. It presents with a series of atypical symptoms and signs stemming from asthenopia, dry eye syndrome, preexisting untreated vision issues and poor screen ergonomics. This review summarizes research data to date to determine whether the concept of DES has been conclusively defined and demarcated as a separate entity and if sufficient guidance is offered on professionals and the lay public. The maturity of the field, grouping of symptoms, examination techniques, treatment and prevention modalities are summarily presented.

Abstract
Visible light is present everywhere in our lives. Widespread use of computers and smartphones has increased the daily time spent in front of screens. What effect does this visible light have on us? Recent studies have shown that short-wavelength blue light (400-450nm) irradiation, similar to UV, inhibits the cell proliferation and differentiation, induces the intracellular oxidative stress, promotes the cell apoptosis and causes some other negative effects. However, it's unusual that directly face to such short-wavelength and high-energy blue light in daily life. Therefore, the effects of blue light with longer wavelength (470nm), lower energy (1, 2 J/cm2) and multiple times (simulated daily use) exposure on cells have been studied in this experiment. In our results, low energy density multiple blue light inhibited cell proliferation and metastatic capability with a weak phototoxicity. Blue light also promoted intracellular reactive oxygen species and caused DNA damage. Furthermore, the melanin synthesis was also promoted by low energy density multiple blue light exposure. Together, these results indicate that longer wavelength and low energy density blue light multiple exposure is still harmful to our cells. Furthermore, prolonged exposure to screens likely induces dull skin through induction of melanin synthesis. These results further mentioned us should paid more attention to controlling the daily use of digital device.

Abstract
Although computer vision syndromes are becoming a major public health concern, less emphasis is given to them, particularly in developing countries. There are primary studies on different continents; however, there are inconsistent findings in prevalence among the primary studies. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence of computer vision syndrome. In this study, the review was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Online electronic databases, including PubMed/Medline, CINAHL, and Google Scholar, were used to retrieve published and unpublished studies. The study was conducted from December 1 to April 9/2022. Study selection, quality assessment, and data extraction were performed independently by two authors. Quality assessment of the studies was performed using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument tool. Heterogeneity was assessed using the statistical test I2. STATA 14 software was used for statistical analysis. A total of 7,35 studies were retrieved, and 45 studies were included in the final meta-analysis. The pooled prevalence of computer vision syndrome was 66% (95% CI: 59, 74). Subgroup analysis based on country was highest in Pakistan (97%, 95% CI: 96, 98) and lowest in Japan (12%, 95% CI: 9, 15). Subgroup analysis based on country showed that studies in Saudi Arabia (I2 = 99.41%, p value < 0.001), Ethiopia (I2 = 72.6%, p value < 0.001), and India (I2 = 98.04%, p value < 0.001) had significant heterogeneity. In the sensitivity analysis, no single study unduly influenced the overall effect estimate. Nearly two in three participants had computer vision syndrome. Thus, preventive practice strategic activities for computer vision syndrome are important interventions.

Abstract
Purpose To analyze surgical results of 32 cases with acute acquired comitant esotropia (AACE) related to prolonged use of digital devices (DDs). Patients and Methods Medical records of cases with AACE related to prolonged use of DDs that had undergone surgery were retrospectively revised. Complete medical history and full ophthalmological examinations before and surgery were obtained for all cases. All cases also underwent neurological examinations using brain and orbital imaging. Motor success was considered as alignment within 10 prism diopters (Δ) at both near and distance. Sensory success was defined as stereopsis ≤60 arcsec. Nineteen cases (Group S) underwent surgery alone and 13 cases were treated with surgery and prism adaptation (Group S+P). Motor and sensory outcomes were compared between groups. Results Mean age at first visit was 22.0 ± 9.0 years and mean daily use of DDs use was 6.3 ± 3.4 hours. Mean angle of preoperative alignment for distance and near were 26.5 ± 13.0Δ and 24.6 ± 16.4Δ, respectively. Surgery was performed at a mean of 23.3 ±3.5 years old and mean angle of alignment at final examination for distance and near were 5.8 ± 7.7Δ and 3.5 ± 5.7Δ, respectively. Final motor and sensory success rate were 84% and 53%, respectively. No significant differences in motor or sensory outcomes were evident between groups at initial or last visit. Conclusion Favorable motor and sensory outcomes were achieved with surgical intervention with and without prism adaptation for AACT related to prolonged use of DDs.

Abstract
Objective: Computer vision syndromes are becoming a major public health concern. Inconsistent findings existed on computer vision syndrome. This systematic review and meta-analysis aimed to estimate the pooled prevalence of computer vision syndrome and identify its determinants. Methods: In this study, the review was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Online electronic databases, including PubMed/Medline, CINAHL, and Google Scholar, were used to retrieve studies from 1 December to 9 April 2022. Quality assessment of the studies was performed using the JBI-MAStARI. RevMan and STATA 14 software were used for statistical analysis. Result: A total of 725 studies were retrieved, and 49 studies were included. The pooled prevalence of computer vision syndrome was 66% (95%, Confidence interval: 59, 74). Being female (Odd Ratio = 1.74, 95% Confidence interval [1.2, 2.53]), improper body posturing while using electronic devices (Odd Ratio = 2.65, 95% Confidence interval [1.7, 4.12]), use of electronic devices out of work (Odd Ratio = 1.66, 95% CI [1.15, 2.39]), no habit of taking breaks (Odd Ratio = 2.24, 95% Confidence interval [1.13, 4.44]), long duration of visual display terminal use (Odd Ratio = 2.02, 95% Confidence interval [1.08, 3.77]), short distance screen (Odd Ratio = 4.24, 95% Confidence interval [2.33, 7.71]), and general ergonomic practice (Odd Ratio = 3.87, 95% Confidence interval [2.18, 6.86]) were associated with increased odds of computer vision syndrome. However, good knowledge (Odd Ratio = 4.04, 95% Confidence interval [2.75, 5.94]) of computer vision syndrome was associated with decreased odds of computer vision syndrome. Conclusion: Nearly two in three participants had computer vision syndrome. Being female, improper body posturing, use of electronics devices out of work, no habit of taking a break, long-hour duration of visual display terminal use, short-distance screen, and general ergonomic practice were associated with increased odds of computer vision syndrome.

Abstract
Background Shifting to online learning during the coronavirus pandemic has increased the number of individuals symptomatic of digital eye strain (DES). This study aimed to determine the frequency and potential risk factors of DES among university staff members and students in this pandemic era. Methods A cross-sectional online survey was conducted during the pandemic, in May and June 2020. The online questionnaire was designed to collect data on DES-related ocular and extraocular manifestations. The survey was sent via social media to the previous year's students and staff within the Faculty of Medicine, Tanta University, Tanta, Egypt. The responses were downloaded and analyzed. Results Of the 412 participants completing the questionnaire, 34 (8.3%) were university staff members with a mean (standard deviation [SD]) age of 36.7 (6.6) years, and 378 (91.7%) were university students with a mean (SD) age of 20.8 (1.8) years. Participants with DES symptoms numbered 294 (71.4%) before the lockdown, increasing to 366 (88.8%) during the last month, with 84 developing new-onset DES. Most participants reported ocular symptoms associated with DES. After the lockdown, both students and staff had a significant prolongation of nighttime digital screen use and TV watching, an increase in the 4-item Patient Health Questionnaire (PHQ-4) severity scale scores, and anxiety and depression, with a reduced duration of daytime reading (all P < 0.05). Students had a significant prolongation of daytime digital screen use and TV watching and an increase in the frequency of eye lubricant use and mean Perceived Stress Scale (PSS)-4 scores (all P < 0.05). Multiple logistic regression analysis revealed that studenthood and increased nighttime screen use were independent risk factors for DES by odds ratios (95% confidence intervals) of 10.60 (2.12 - 53.00) and 3.99 (1.71 - 9.34), respectively (both P < 0.05). Conclusions Lockdown and closure of the university, with a shift to online learning, increased the exposure of staff and students to digital screens and the number of individuals with DES. Studenthood and prolonged nighttime digital screen use were independent risk factors for DES. Further studies investigating the prevalence and risk factors of DES, comparing similar data during and after the pandemic, may reveal other aspects of DES caused by virtual reality-based training.

Abstract
IMPORTANCE To limit the spread of COVID-19, numerous restrictions were imposed on youths, including school closures, isolation requirements, social distancing, and cancelation of extracurricular activities, which independently or collectively may have shifted screen time patterns. OBJECTIVE To estimate changes in the duration, content, and context of screen time of children and adolescents by comparing estimates taken before the pandemic with those taken during the pandemic and to determine when and for whom screen time has increased the most. DATA SOURCES Electronic databases were searched between January 1, 2020, and March 5, 2022, including MEDLINE, Embase, PsycINFO, and the Cochrane Central Register of Controlled Trials. A total of 2474 nonduplicate records were retrieved. STUDY SELECTION Study inclusion criteria were reported changes in the duration (minutes per day) of screen time before and during the pandemic; children, adolescents, and young adults (≤18 years); longitudinal or retrospective estimates; peer reviewed; and published in English. DATA EXTRACTION AND SYNTHESIS A total of 136 articles underwent full-text review. Data were analyzed from April 6, 2022, to May 5, 2022, with a random-effects meta-analysis. MAIN OUTCOMES AND MEASURES Change in daily screen time comparing estimates taken before vs during the COVID-19 pandemic. RESULTS The meta-analysis included 46 studies (146 effect sizes; 29 017 children; 57% male; and mean [SD] age, 9 [4.1] years) revealed that, from a baseline prepandemic value of 162 min/d (2.7 h/d), during the pandemic there was an increase in screen time of 84 min/d (1.4 h/d), representing a 52% increase. Increases were particularly marked for individuals aged 12 to 18 years (k [number of sample estimates] = 26; 110 min/d) and for device type (handheld devices [k = 20; 44 min/d] and personal computers [k = 13; 46 min/d]). Moderator analyses showed that increases were possibly larger in retrospective (k = 36; 116 min/d) vs longitudinal (k = 51; 65 min/d) studies. Mean increases were observed in samples examining both recreational screen time alone (k = 54; 84 min/d) and total daily screen time combining recreational and educational use (k = 33; 68 min/d). CONCLUSIONS AND RELEVANCE The COVID-19 pandemic has led to considerable disruptions in the lives and routines of children, adolescents, and families, which is likely associated with increased levels of screen time. Findings suggest that when interacting with children and caregivers, practitioners should place a critical focus on promoting healthy device habits, which can include moderating daily use; choosing age-appropriate programs; promoting device-free time, sleep, and physical activity; and encouraging children to use screens as a creative outlet or a means to meaningfully connect with others.

Abstract
Although mobile technologies are a fundamental part of daily life, several studies have shown increased use of electronic devices, TV, and gaming during childhood in conjunction with the COVID-19 pandemic. The virus affected almost every country, causing uncertainty about the future, social isolation, and distress. This narrative review has searched the scientific literature in the field focusing on children. A non-systematic literature review was conducted in May 2022. Various databases were employed to conduct the document research for this paper, such as "Google Scholar", "PubMed", "Web of Science". Keywords for the search included "screen time", "media", "digital use", "social media", "COVID-19", "pandemic", "lockdown", "children", "effect of media on children during COVID". It was found that both children and adolescents seem to have used technologies to confront struggles provoked by COVID-19, such as the onset or exacerbation of symptoms of anxiety, depression, and attention-deficit/hyperactivity disorder. However, moreover, other studies have suggested that increased media use can have positive effects on children depending on usage and monitoring by the parents.

Abstract
Myopia is already one of the leading causes of permanent vision impairment, including blindness, and the COVID-19 pandemic has exacerbated the global myopia-related burden among children owing to home confinement, increased screen time (e-learning), and decreased outside activities. To reverse the rising trend of myopia and myopia-related blindness, collaborative efforts are required. There is a wealth of evidence-based medicine (EBM) data on the epidemiology of myopia and effective interventions, but very little has been published on the clinicians' roles and responsibilities. However, this aspect is critical because preventing the onset and progression of myopia necessitates extensive health promotion and advocacy efforts among decision-makers. Only broad medical expert collaboration can bring about the necessary changes in children's lifestyle and education. This article discusses clinicians' critical roles in preventing the onset and progression of myopia.

Abstract
The coronavirus disease 2019 outbreak has impacted many educational institutions by imposing restrictions on offline or in-person lessons. Many students were stressed by "the loss of everyday life" due to the pandemic, and it is important to examine the impact of this loss on adolescents' mental health. This study aimed to investigate the factors that affect students' mental health during the pandemic from various perspectives. A total of 166 medical students participated in this study. Participants completed questionnaires about their demographics, life stress, mental health, and stress factors during in-person and online lecture days. Participants were divided into 2 groups, those with low and high mental health. The researchers compared independent variables between the groups using the χ2 test or Fisher's exact test. Multiple logistic regression analysis was performed, with mental health as the dependent variable. The multiple logistic regression analysis indicated that increased time spent online was significantly associated with mental health (P < .05). Human relations and the inability to meet/talk with friends trended toward a significant association with mental health (P < .1). The students who were not stressed about the increased time spent online were at a risk of low mental health. The students who appreciated interacting with others experienced more stress during the lockdown. To reduce students' stress on online days, teachers should devise a lecture style with frequent breaks and introduce active learning. The findings of this study will contribute to addressing students' low mental health and reducing their stress during the coronavirus disease 2019 pandemic.

Prevalence of Computer Vision Syndrome among School-Age Children during the COVID-19 Pandemic, Saudi Arabia: A Cross-Sectional Survey. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9111718. [PMID: 36360446 PMCID: PMC9689306 DOI: 10.3390/children9111718] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 10/21/2022] [Accepted: 11/03/2022] [Indexed: 11/11/2022]
Abstract
Background: Computer vision syndrome (CVS) can be described as ocular-related symptoms that result from prolonged exposure and use of computers, smartphones, tablets, and other devices with digital displays. The main objective of this study was to investigate the prevalence of CVS among school-age children, the associated signs, risk factors, and the association between the disease before and during the COVID-19 pandemic in the Jazan region of Saudi Arabia. Methods: The study employed a descriptive cross-sectional research design. The targeted population was school-going children aged 6 to 18 in the Jazan region in the Southwest of Saudi Arabia. A sample of 440 participants was selected to represent the population under study. Data were collected using self-administered questionnaires. Sociodemographic characteristics were recorded, such as age, gender, education level, parents’ education, occupation, frequency, and intensity of eye symptoms if present. Results: Most of the participants were adolescents between 16 and 18 and at a high-school education level. According to the total symptoms score, the CVS prevalence was 35.4%. Prevalence of CVS significantly affects age, gender, and school level (p < 0.05 for all). A similar significant association was reported between the symptoms experienced before and during COVID-19 and the CVS (p < 0.05). Conclusion: A total of 407 adolescents aged 16−18 responded to the questionnaire (response rate of 92.5%; 407 out of 440). The study estimated the prevalence of CVS among school-going children in Jazan to be low. The main signs associated with CVS included headache, tearing, itchiness, blurred vision, eye redness, eye pain, and dryness. The attitude of children toward their health condition during the COVID-19 pandemic and the prevalence of CVS have a significant relationship.

Eye Habits Affect the Prevalence of Asthenopia in Patients with Myopia. J Ophthalmol 2022; 2022:8669217. [PMID: 36300162 PMCID: PMC9592227 DOI: 10.1155/2022/8669217] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 08/09/2022] [Accepted: 10/06/2022] [Indexed: 11/17/2022] Open
Abstract
Purpose This study aims to explore the risk factors of asthenopia in the myopic population. Methods In this cross-sectional study, myopia patients were inquired about their eye habits and were requested to complete an asthenopia questionnaire and ocular examinations. Age, gender, occupation, anisometropia, eye care education, weekly outdoor activity time, duration of continuous near work, daily screen time, dry eye, near phoria, and binocular accommodative facility were calculated using the Student's test-test, Mann Whitney U test, and Pearson's chi-square test. Spherical equivalents and astigmatism were calculated using a generalized estimating equation. Binary logistic regression was performed on factors with a p-value <0.05. Results Of the 65 myopic patients, 57% showed asthenopia, 52% experienced blurry vision, 37% felt their eyes hurt or sore, and 28% felt tired when performing close work. Asthenopia patients were older than patients without asthenopia (Z = −2.887, p=0.004). Daily screen time, continuous near-work time, eye care education, and dry eye were positively correlated with asthenopia (χ2 = 8.64, p=0.003; χ2 = 13.873, p < 0.001, χ2 = 9.643, p=0.002; χ2 = 7.035, p=0.008). After eliminating collinearity, eye care education and continuous near-work time were identified as independent risk factors of asthenopia, with odds ratios of 0.115 and 4.227, respectively. Conclusion This study shows that receiving eye care education from schools and hospitals and limiting near-work duration to less than 45 minutes per session could reduce the occurrence of asthenopia in myopic patients. This approach may be a more economical and convenient way for myopic people to relieve asthenopia.

Abstract
BACKGROUND The rapid increase increased, in using of video display terminals during the COVID-19 pandemic predisposes users to a variety of health problems restricted to visual problems and including various musculoskeletal problems, collectively known as computer vision syndrome (CVS) or computer vision syndrome. AIM This study aims to ascertain university students' awareness of computer vision syndrome at Al-Baha University, including the nature, sources, accuracy, and completeness of information, as well as the attitudes towards CVS, and mitigative practices. METHODS This study used a descriptive cross-sectional design and a convenient sample of 310 (80.0% male) students drawn from Al Baha University campuses. Data were collected using self-administered questionnaires. RESULTS The mean age of the participants was 23.51 years (SD=5.42). The results show that 78.7%, 66.1%, and 11.6% received CVS information from social media, mass media, and family, respectfully. Despite 70% of respondents being aware of CVS manifestations, between 42% to 67% of those sampled had accurate and complete information about the meaning, causes, prevention, and management of the syndrome. More than a third of the participants had either a good (62.9%) or average (29%) total knowledge of CVS. Less than 15% had incorrect information. On average, 62.5% of respondents engaged in preventive or mitigative behaviours/activities as opposed to 37.5% who did not, but only 44% believed CVS was a serious health threat. 65.2% of the studied students had a satisfactory total practice score. The regression analysis showed that the coefficients of marital status and faculty were a statistically significant association with the total knowledge score. CONCLUSION CVS awareness is acceptably high, but there is a low preventive/mitigative behaviors as well as a low realization of CVS' long-term health problems. This is why increasing CVS awareness and implementing interventions such as the 20-20-20 rule could be effective at Al Baha University.

Abstract
The aim of our study was to compare computer visual syndrome (CVS) in a tweenager student population who use tablets and laptops only to play versus CVS in tweenagers who use these digital devices at school to study, in addition to playing. The tests performed were a validated survey for children for the detection of CVS and accommodative and vergence tests. The CVS item questionnaire was divided into four main groups based on questions concerning the following: (I) the digital device usage time, (II) musculoskeletal and ergonomic nature, (III) visual symptoms, and (IV) ocular surface symptoms. The high-demand digital device group showed worse punctuation in all item groups. From the optometric perspective, when the subjects were classified according to the CVS, high-demand participants presented a clear tendency to exophoria with statistically significant differences in distance vision (−1.94 ± 4.48 Δ) and near vision (−5.78 ± 8.62 Δ) (p < 0.01). Our results establish a relationship between the increased use of electronic devices and computer vision syndrome in the preadolescent population. In addition, this situation is related to the presence of visual, accommodative, and binocular dysfunctions that could affect the efficiency of the visual system.

J Family Med Prim Care 2022; 11:5387-5392. [PMID: 36505557 PMCID: PMC9731063 DOI: 10.4103/jfmpc.jfmpc_1771_21] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 12/16/2021] [Accepted: 03/26/2022] [Indexed: 11/06/2022] Open
Abstract
Background During the COVID-19 pandemic lockdown, the normal daily routine activities of children were restricted as a result of the need to stay indoors. Consequently, children were forced to attend online classes provided by their educational institutions at their homes. Due to the subsequent increased screen exposure, children have started complaining of blurred vision, headache, and symptoms related to computer vision syndrome (CVS), predisposing them to myopia. Objective To determine the prevalence of CVS symptoms, such as blurring of vision, headache, and watery eyes in children, due to increased screen time during the lockdown period of the COVID-19 pandemic. Methods This was a non-randomized, questionnaire-based study conducted at the ophthalmology department of a tertiary care pediatric hospital. The participants were parents of children aged between 6 and 16 years attending regular school. Enrolled parents were interviewed through a Google Form after completing the online consent in English. Eligible participants were recruited by a circulation of this form through multiple groups on social media, namely, WhatsApp and email. Results A total of 145 parents participated in the study. The children were classified according to the duration of exposure to digital devices ranging from less than 2 h to less than 6 h daily. There was a significant association between the increase in the number of activities and the development of CVS symptoms in children (r = 0.15; P = 0.036). Conclusion COVID-19 lockdown has largely affected the lifestyle of school-going children by significantly decreasing their outdoor activities and increased online exposure to screen, thus predisposing them to myopia, ocular ill health, and increased dry eye symptoms. Increased exposure to online screen was detected during this lockdown period of the COVID-19 pandemic; this strongly supports the recommendation to decrease the number of hours of online screen exposure and encourages students to regularly get engaged in outdoor activities.

Abstract
Purpose To assess the connection between the prevalence of asthenopia and the use of electronic devices in Jazan, Saudi Arabia, during the COVID-19 pandemic. Patients and Methods Asthenopia prevalence and its connection to electronic screens during the COVID-19 pandemic were evaluated in an analytical, cross-sectional investigation among the Jazan population. The sample population included 784 participants. Due to the COVID-19 pandemic, a pre-tested, organized, and self-administered questionnaire was used as the study method. Social media invitations were used to contact the sample group. Results Of the 784 participants, 587 (74.96%) had asthenopia symptoms after using digital devices at the end of the day. A total of 56.30% used digital gadgets for > 6 hours each day, whereas 55.36% spent <2 hours per day reading papers or books or writing. Daily usage of digital gadgets did not significantly differ from asthenopia (p=0.46), as well as reading papers, books, or writing and asthenopia (p=0.098). A total of 45.92% of the study population maintained digital devices/books at a distance <25 cm, which was significantly associated with symptoms of asthenopia (p=0.048). Furthermore, 90.10% of the sample population used laptops, cellphones, and iPads before going to bed or after turning off lights. A total of 63.52% preferred using devices while lying in bed. There was no positive link between asthenopia symptoms and cellphone usage at bedtime or after turning off lights (p=0.028). Conclusion Digital technology is used by people of all ages for a wide range of daily activities, including education, employment, business, and recreation. We concluded that this group had a high prevalence of asthenopia, especially during the COVID-19 pandemic. The high frequency of asthenopia emphasizes the significance of conducting public awareness campaigns concerning asthenopia symptoms and prevention methods.

Abstract
Introduction Digital eye strain, which is often ignored by the public, has emerged as a "Shadow Pandemic" in the era of the COVID-19 pandemic. Aim The current paper is aimed at discussing the ill effect of digital screens on eyes in the wake of the COVID-19 pandemic. Methodology A literature search was done using "PubMed," "Google scholar", and "Scopus" using key terms like "Digital Eye Strain," "Eyestrain," or "Computer Vision Syndrome." Relevant articles were identified and included to support the argument for this narrative review. Results Studies conducted in the UK reported that 68% of children extensively use computers, while 54% undertake online activities after the age of 3. Similar studies estimated 4 h and 45 min per day of screen exposure time among adults in the UK. Indian studies reveal that the prevalence of DES is 69% in adults and 50% in children respectively. Indian ophthalmologists found that computer-using and specialized ophthalmologists were more informed of symptoms and diagnostic signs but were misinformed about treatment modalities. The use of social media and multitasking is particularly prominent among younger adults, with 87% of individuals aged 20-29 years reporting the use of two or more digital devices simultaneously. It has been observed that the use of computer glasses corrects refractive errors and helps in the reduction of symptoms, while precision spectral filters help in reducing symptoms of micro-fluctuation of accommodation. Conclusion We concluded that DES is emerging globally as a "Shadow Pandemic" and it is high time to respond. Community ophthalmologists, public health authorities, and educational sectors especially should be involved to prevent this.
