What is digital eye strain?
Digital eye strain, also called computer vision syndrome, is a group of symptoms caused by prolonged screen use. It does not cause lasting damage to the eyes, but it can be uncomfortable and affect concentration during the day.
Symptoms of digital eye strain
Symptoms build up during or after screen time.
- Tired, sore or aching eyes
- Dry or gritty eyes from reduced blinking
- Headaches and difficulty focusing
- Temporary blurred vision or neck and shoulder ache
What causes digital eye strain, and who is at risk?
We blink less and focus at a fixed close distance when using screens, which tires the focusing muscles and dries the surface of the eye. Glare, poor lighting, small text, and an uncorrected glasses prescription all make it worse.
Self-care and prevention
Simple habits make a big difference: follow the 20-20-20 rule by looking at something 20 feet away for 20 seconds every 20 minutes, blink fully and use lubricating drops, position the screen slightly below eye level, reduce glare, and make sure your glasses prescription is up to date.

Frequently asked questions
Is digital eye strain harmful?
Digital eye strain is uncomfortable but does not cause lasting damage to the eyes. Symptoms ease with breaks, blinking, and a better screen setup.
What is the 20-20-20 rule?
Every 20 minutes, look at something about 20 feet away for 20 seconds. This relaxes the focusing muscles and helps reduce screen-related eye strain.
Do screens damage your eyes?
Current evidence suggests screens cause temporary strain rather than permanent damage in adults. In children, more outdoor time is encouraged to help reduce the risk of short-sightedness.
