Summary
This review examines Computer Vision Syndrome (CVS) and the broader effects of prolonged digital screen exposure on ocular health, including eye strain, dryness, and induced myopia, as well as circadian rhythm disruption. It recommends evidence-based preventive strategies such as regular breaks, ocular ergonomics, ambient lighting control, and blue light filters to mitigate visual and circadian health risks.
Key Findings
- Prolonged digital screen exposure is associated with Computer Vision Syndrome (CVS), encompassing eye fatigue, dryness, and digitally-induced myopia.
- Blue light from screens is identified as a contributor to sleep disruption and circadian desynchronization across multiple age groups.
- Recommended interventions include blue light filters, regular screen breaks, improved ergonomics, and ambient lighting management, though the review notes the evidence base for blue light filters specifically remains under scrutiny.
- Literature reviewed spans 2014–2024 across PubMed, SciELO, Google Scholar, and Medline; no specific effect sizes or p-values were reported in the abstract.
