Summary
Digital eye strain affects an estimated 50% or more of computer users, presenting with symptoms related to accommodative stress and dry eye; blue-light-blocking spectacle lenses have been explored as a management tool with mixed results. Eye care practitioners should consider a multi-faceted approach including refractive correction, dry eye management, and screen break protocols rather than relying solely on blue-light filtering lenses.
Key Findings
- Prevalence of digital eye strain (DES) among computer users is estimated at 50% or higher.
- Blue-light-blocking spectacle lenses have shown mixed results across studies for reducing DES symptoms.
- Objective measures of visual fatigue include critical flicker-fusion frequency, blink rate, accommodative function, and pupil characteristics, though correlations with subjective symptom reports are inconsistent.
