How to Avoid Digital Eye Strain --Treatment and Relief

Start with the reason your eyes feel tired

Digital eye strain can involve dryness, fluctuating blur, headaches, or difficulty sustaining near work. We assess prescription, focusing, eye coordination, tear film, and the working environment. Screen discomfort is not proof that blue light is damaging the eyes.

Make your setup comfortable

• Use text large enough to read comfortably and adjust the screen distance to your prescription.
• Reduce reflections and avoid a screen that is much brighter than its surroundings.
• Take regular comfortable breaks and blink fully; avoid prolonged, unbroken near work.
• Keep fans and vents from blowing directly across the eyes.
• Ask whether a computer-distance prescription or dry-eye treatment is appropriate.

How strong is the evidence for 20-20-20?

Looking about 20 feet away for 20 seconds every 20 minutes is a memorable reminder to take breaks. The exact schedule is not a proven cure. A small two-week reminder study reported symptom improvement, while a separate controlled reading-task study found no benefit from scheduled 20-second breaks. The studies used different methods.

Choose lenses for the task

A suitable prescription and comfortable fit matter. Blue-filtering lenses have not consistently improved eye strain compared with clear lenses; read our evidence update and the randomized trial. Arrange an examination for continuing symptoms.
