Question 1

What is digital eye strain?

Accepted Answer

Digital eye strain (also called computer vision syndrome) is a group of eye and vision symptoms — burning, dryness, blurred vision, headaches, tired eyes — caused by prolonged screen use. It comes mainly from reduced blinking, sustained focus at one distance, glare, and dry eyes, not from blue light.

Question 2

Is blue light causing my eye strain?

Accepted Answer

Almost certainly not. The American Academy of Ophthalmology states that blue light from screens does not damage the eyes, and blue-light-blocking glasses have not been shown to reduce eye strain. The real drivers are blinking less, focusing at one distance for long periods, glare, and dryness.

Question 3

How do you fix computer eye strain?

Accepted Answer

The evidence-based fixes are simple: follow the 20-20-20 rule (every 20 minutes look 20 feet away for 20 seconds), blink deliberately, reduce glare, use artificial tears if your eyes feel dry, keep the screen an arm's length away and slightly below eye level, and make sure your glasses prescription is current. Symptoms that persist deserve an eye exam.

Question 4

When should I see a doctor about eye strain?

Accepted Answer

See an eye-care professional if eye strain is frequent or severe, doesn't ease with breaks and the usual measures, comes with persistent headaches or double vision, or if your vision has changed. Ongoing strain can also signal an outdated prescription, dry eye disease, or a focusing problem worth correcting.
