Eye exercises: what the research says, and how to keep track of the ones you were prescribed

The short answer

Eye exercises do not correct nearsightedness, farsightedness, astigmatism or age-related reading problems, according to the American Academy of Ophthalmology. Their best-supported use is convergence insufficiency, an eye teaming problem, where exercises supervised by an optometrist or orthoptist have strong trial evidence. For comfort during screen work, regular breaks such as the 20-20-20 rule can reduce strain.

This guide summarises what eye exercises can and can't do, the techniques clinicians commonly prescribe, what the research shows, and how to keep a simple record of the exercises you've been given.

What eye exercises can and can't do

Eye exercises work on how the eyes move, team and focus together. They do not change the shape of the eye, which is what causes most blurry vision.

Exercises are sometimes also used in rehabilitation after certain surgeries or injuries, as part of a plan from the treating team.

Techniques clinicians commonly prescribe

These are the exercises you are most likely to be given. They are described here so you recognise them, not as a program to follow on your own. Your clinician decides which ones, how often and for how long.

• Pencil push-ups: slowly bringing a small target toward the nose while keeping it single. Used for convergence insufficiency. How pencil push-ups and the Brock string work.
• Brock string: a cord with beads used to practise and check eye teaming.
• Near and far focusing: switching focus between a close and a distant target.
• Jump convergence and other orthoptic exercises: prescribed and reviewed by an orthoptist or optometrist.
• Screen breaks and blinking: the 20-20-20 rule for digital eye strain.

Palming and the Bates method are popular online, but there is no evidence they improve eyesight. See eye exercise myths.

What the research shows

• CITT (2008): 221 children aged 9 to 17 with convergence insufficiency were treated for 12 weeks. Office-based therapy with home practice was successful or improved in 73 percent, compared with 43 percent for home pencil push-ups, 33 percent for home computer therapy with push-ups, and 35 percent for placebo.
• Cochrane review (2020): 12 randomised trials with 1,289 participants. In children, office-based therapy was more effective than pencil push-ups or placebo, with high-certainty evidence. Evidence in adults was less clear.
• Screen breaks (2022): in a study of 29 computer users, break reminders reduced digital eye strain and dry eye symptoms, but the benefit was gone a week after people stopped taking breaks.
• Refractive error: the American Academy of Ophthalmology says there is no evidence that exercises change uncorrected visual acuity.

Doing prescribed exercises safely

• Do only the exercises your eye care professional has given you, at the frequency they set.
• Stop and tell your clinician if you get eye pain, headache, dizziness or nausea.
• Some people find symptoms feel worse at first. The NHS leaflet for convergence insufficiency says this can happen before they improve. Check with your orthoptist if you're unsure.
• Sudden double vision, vision loss or a drooping eyelid needs urgent care, not exercises. See warning signs.

Keeping track between appointments

The Cochrane review found that home exercise programs were followed less consistently than supervised ones. A simple log of what you did and how it felt gives your clinician a clearer picture at your next review.

The Ocufuse Practice log records which exercise you did and when, alongside your eye photos and notes, and adds it to your Doctor Brief. It does not prescribe, adjust or teach exercises. How the eye exercise log works.

Frequently asked questions

Do eye exercises improve vision?

Eye exercises do not correct nearsightedness, farsightedness, astigmatism or presbyopia, according to the American Academy of Ophthalmology. Supervised exercises have good evidence for convergence insufficiency, an eye teaming problem.

How long do eye exercises take to work for convergence insufficiency?

Programs commonly run for several weeks to a few months. The CITT trial used a 12-week program. Your orthoptist or optometrist sets the schedule and reviews progress.

Can I do eye exercises without seeing a doctor?

Screen breaks are safe for anyone. Exercises for a specific condition should be prescribed after an eye examination, so the problem is correctly identified and the right exercises are chosen.

Are eye exercise apps effective?

Apps that promise better eyesight from exercises are not supported by evidence for refractive error. Apps are most useful for reminders and for logging exercises your clinician prescribed.
