Tired, dry or burning eyes after hours on your phone? Learn the symptoms of digital eye strain (computer vision syndrome) and 10 practical fixes, from the 20-20-20 rule to the right glasses.
Mobile phones, laptops and online classes mean many of us now spend six to ten hours a day looking at screens. The result is a set of symptoms called digital eye strain or computer vision syndrome. The good news: simple habits and the right correction relieve it for most people.
Symptoms of Digital Eye Strain
- Tired, heavy or burning eyes
- Dry, gritty eyes, or paradoxically watery eyes
- Blurred vision when looking up from the screen
- Headaches, especially around the forehead
- Neck and shoulder pain
- Difficulty sleeping after late-night screen use
Why Screens Strain the Eyes
- Fewer blinks: we blink far less while concentrating on a screen, so tears evaporate and eyes dry out
- Constant near focus: the focusing muscles work non-stop at close range
- Small text and glare: phones are held close, and screen glare adds strain
- Uncorrected power: small amounts of astigmatism or long-sightedness make screen work harder
10 Practical Fixes
- Follow the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds.
- Blink fully: make a habit of slow, complete blinks.
- Hold your phone further away, about 40 cm, and increase the font size.
- Set brightness to match the room; avoid a bright screen in a dark room.
- Use night mode in the evening and stop screens an hour before sleep.
- Position laptops slightly below eye level and an arm’s length away.
- Reduce glare from windows and tube lights; consider an anti-reflective coating.
- Keep the air moist; do not let fans or AC blow directly on your face.
- Use preservative-free lubricating drops if advised for dryness. See our dry eye guide.
- Get an eye test to correct even small errors. Many people with screen strain simply need the right glasses.
Do Blue-Cut Glasses Help?
Blue-cut lenses filter part of the blue-violet light from screens and usually come with anti-glare coating. Many users report more comfort, though the biggest gains come from correct power, breaks and blinking.

Children and Screens
Children’s eyes are still developing, and long close-up screen time with little outdoor play is linked to rising short-sightedness. See Myopia in Children.
Frequently Asked Questions
Can screens permanently damage my eyes?
Current evidence suggests screen use causes strain and dryness rather than permanent damage in adults, but habits matter, especially for children.
Should I wear glasses only for the computer?
If your prescription is small, you may need glasses only for screen or near work. The optometrist will advise based on your test.
