Eye strain from screens results from continuous near focusing, reduced blink rate, and suboptimal viewing conditions when using computers, tablets, or phones. It can affect both adults and children.
Main Factors
Uncorrected refractive error, unsuitable spectacles, glare, and small or high‑contrast text force the eyes to work harder. Concentration on screens naturally reduces blinking, causing dryness and discomfort.
- Sustained viewing at one distance overworks the focusing muscles
- Poor posture and ergonomics contribute to neck and shoulder pain
- Multifocal lenses may not align optimally with the screen without proper fitting
- High screen brightness in dark rooms can increase glare and strain
Reducing the Problem
Adjusting screen height and distance, using up‑to‑date spectacles or dedicated computer lenses, and taking regular breaks help relieve symptoms. Lubricating drops may be useful for associated dryness.
- Keep screens at arm’s length and just below eye level
- Minimise reflections with matte screens or anti‑glare filters
- Apply the twenty-twenty-twenty rule throughout screen sessions
- Arrange an eye examination if discomfort continues despite these measures
