A Study of Full-Spectrum Screen Lighting for Reducing Screen-Related Eye Fatigue and Dry Eye

This study will evaluate whether full-spectrum screen bar lighting can reduce eye fatigue and dry eye symptoms after a standardized screen task. Prolonged screen use is common in daily work and study and may cause blurred vision, eye soreness, dryness, headache, and reduced attention. Light environment may be one way to improve visual comfort during screen use, but more controlled clinical evidence is needed. In this randomized, parallel-group controlled study, 112 healthy adult participants will be assigned to either a full-spectrum screen bar lighting group or a brightness-matched control group without screen bar lighting. Participants in both groups will complete an approximately 2-hour standardized screen task in a controlled laboratory environment. The study will compare changes before and after the task in objective and subjective measures of visual fatigue and dry eye, including critical flicker fusion frequency, visual fatigue questionnaire scores, eye movement and blinking parameters, pupil parameters, tear film-related measurements, and dry eye symptom scores. Safety and discomfort during the study will also be recorded.

Digital Eye Strain in Online Learning and Remote Work Environments: A Systematic Review

This systematic review aims to evaluate the prevalence of digital eye strain (DES) among individuals engaged in online learning and remote work, identify associated demographic, behavioral, environmental, and ocular risk factors, and summarize evidence regarding preventive and therapeutic management strategies. Electronic databases including PubMed/MEDLINE, Scopus, Web of Science, Embase, Cochrane Library, and Google Scholar were systematically searched for relevant studies published from January 2020 onward. Eligible studies included observational and interventional studies involving online learners or remote workers that reported the prevalence, risk factors, or management of DES. Two independent reviewers performed study selection, data extraction, and quality assessment. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Where appropriate, quantitative synthesis using a random-effects meta-analysis was planned; otherwise, findings were synthesized narratively. The review is intended to provide evidence-based recommendations for reducing the burden of digital eye strain in educational and occupational settings characterized by prolonged digital device use.

Protecting the Eyes of Gamers With Lubricating Eyedrops

The excessive use of screens particularly amongst digital gamers can adversely impact the health of the surface of the eyes with symptoms and signs of surface damage. While strategies including limiting screen time exist, these may be ineffective given the widespread rise of digital device use and gaming culture in the modern era. There is limited evidence for the protective effect of lubricating eyedrops on the ocular surface for handheld console and computer gamers. The aim of this study is to investigate the protective effect of a lubricating eyedrop (TheaLoz Duo) on the surface of the eyes in handheld console and computer gamers. The main question it aims to answer is whether TheaLoz Duo could protect the surface of the eyes from dessication and alleviate symptoms of dry eye disease in handheld console and computer gamers. Participants will receive either the lubricating eyedrop first for 1 month, followed by a control condition (no eyedrops) for another month, or the other way round. Participants will attend 3 visits in total, each separated by 1 month apart. During each visit, routine clinical assessments of the front of the eye will be conducted. Subsequent findings from this timely study will help improve care of the surface of the eyes for a growing population of gamers worldwide.

Effects Of Optimized Blinking Training on Visual Function and Tear Film Parameters in Individuals With CVS

"Computer vision syndrome (CVS), refers to a range of eye and vision issues caused by extended use of computers, tablets, e-readers, and smartphones. Computer users experience visual symptoms, such as eyestrain, headaches, eye discomfort, dry eyes, double vision, and blurred vision, especially after long periods of looking at screens, whether up close or at a distance.

Risk Factors Among Nursing Students Regarding Computer Vision Syndrome

This study aims to evaluate the prevalence of computer vision syndrome and its associated risk factors among nursing students.
