Lactic Acid Bacteria for Reducing Blue Light-Induced Eye Fatigue

With the widespread use of digital devices and prolonged screen exposure, digital eye strain (DES), also known as computer vision syndrome, has become a global public health concern. Emerging evidence suggests that the gut-eye axis may play an important role in ocular health, as gut microbiota imbalance is associated with systemic inflammation and oxidative stress. Specific probiotics may help alleviate eye discomfort through modulation of immune responses and enhancement of antioxidant defense mechanisms. This randomized, double-blind, placebo-controlled study aims to evaluate the efficacy of supplementation with specific probiotics, Bifidobacterium longum BL531 and Lactobacillus reuteri LR1349, in improving digital eye strain symptoms in adults.

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.

Efficacy of Investigator Product for the Amelioration of Digital Eye Strain in Children

Computer vision syndrome (CVS), also referred to as Digital eye strain (DES), is a group of eye and vision problems caused by prolonged use of electronic devices. The American Optometric Association (APA) defines DES as a group of eye and vision-related problems caused by prolonged computer, tablet, e-reader, and cell phone use. Currently, for more than 20 years, DES has been recognised as a public health issue, and the terms DES are also used to describe the condition, attributed to the wide range of digital devices associated with potential problems.
