Summary
Digital eye strain (DES) affects 50% or more of computer users and encompasses ocular symptoms from accommodative stress and dry eye, with significant implications for workplace lighting and display design. Lighting designers and employers should consider luminance contrast management in workspaces, regular screen breaks, and evidence-based interventions to reduce visual fatigue among screen workers.
Key Findings
- Prevalence of digital eye strain (computer vision syndrome) estimated at 50% or more among computer users
- DES symptoms fall into two categories: accommodative/binocular vision stress and external dry eye symptoms
- Objective measures used to index visual fatigue include critical flicker-fusion frequency, blink rate, accommodative function, and pupil characteristics
- Blue light-filtering spectacle lenses have shown mixed results in treating DES based on recent studies
- Correlations between objective and subjective measures of visual fatigue are not consistently apparent

Workplace Performance: DES affects vocational computer users with economic impact on productivity, linking visual comfort to work performance.
