Digital Eye Strain: How to Protect Your Eyes from Screens

Hours of screen time for work, study and entertainment can cause tired eyes, blurred vision, headaches and dryness. This is often called digital eye strain. Simple habits and settings make a big difference.

Common symptoms

  • Dry, burning or watery eyes
  • Blurred vision after screen use
  • Headaches
  • Neck and shoulder pain
  • Difficulty focusing

The 20-20-20 rule

Every 20 minutes, look at something 20 feet (about 6 metres) away for 20 seconds. This relaxes the eye muscles used for close focus. Set reminders or use Focus sessions to help.

People blink much less when staring at screens, which dries the eyes. Consciously blink fully and often.

Screen position

  • Keep the screen about an arm's length away.
  • Place the top of the screen at or slightly below eye level.
  • Avoid glare from windows or lights behind you.

Brightness and text

  • Match screen brightness to the room.
  • Increase text size so you don't lean forward.
  • Use dark mode or Night Light in the evening. See Windows dark mode and Night Light.

Phone habits

  • Don't use phones in complete darkness.
  • Hold the phone further away; iPhone's Screen Distance feature can remind you.
  • Take breaks from scrolling. See Digital Wellbeing and Screen Time.

Children

Encourage outdoor play, which research links to healthier eye development, and set screen breaks.

What about blue light glasses?

Evidence that blue light glasses reduce eye strain is limited. Breaks, blinking and good setup matter more. Reducing blue light in the evening may help some people sleep better.

See an eye specialist if

  • Symptoms continue despite changes.
  • You have persistent headaches or blurred vision.
  • You haven't had an eye test in a long time; uncorrected vision problems make strain worse.

Set up an eye-friendly workspace

  • Lighting: use soft ambient light; avoid working in a dark room with a bright screen.
  • Glare: position screens perpendicular to windows. Use curtains or blinds.
  • Screen cleanliness: dust and smudges reduce clarity; clean screens gently.
  • Font and zoom: use Ctrl + Plus in browsers to enlarge text on websites.
  • Humidity: air conditioners and fans can dry eyes; avoid airflow directly on your face.

For students and gamers

Long study sessions and gaming marathons are common causes of eye strain. Build breaks into routines: stand and look out of a window between chapters or matches. Set a timer if needed. Stay hydrated, and don't skip sleep; tired eyes strain more easily.

Posture matters too

Eye strain often comes with neck and shoulder pain. Sit with your back supported, feet flat, and screen at eye level. Laptop users benefit from a stand plus external keyboard and mouse. Gentle neck and shoulder stretches during breaks help.

Glasses for computer work

If you wear glasses, tell your eye specialist how much time you spend on screens. Some people benefit from lenses designed for intermediate (screen) distance, especially after age 40.

Frequently asked questions

Does screen use permanently damage eyes?

Eye strain is usually temporary, but symptoms deserve attention.

Do eye drops help?

Lubricating drops can help dryness; ask a pharmacist or doctor which is suitable.
