Eye strain — sometimes called digital eye strain or asthenopia — describes discomfort and fatigue in the eyes from prolonged use. It is not harmful in the long term but can be uncomfortable and disruptive.

  • Adjust screen position (slightly below eye level, 20–28 inches away)
  • Reduce glare with anti-reflective screens or filters
  • Use proper lighting — neither too bright nor too dim
  • Blink consciously to keep eyes lubricated
