Does vision therapy really help? For one condition, the research is strong: office-based vision therapy helps convergence insufficiency, especially in children. For many other claims, such as improving reading, the evidence is weak or negative. Vision therapy is a clinical treatment by eye-care professionals. VisionUp is a wellness app, not vision therapy.
Introduction
Have you ever wondered if vision therapy is just a trend or a genuine solution? Some practices promote it for reading problems, headaches and more. What does the research actually say?
In this article, we summarize the research, explain how vision therapy works, and list the questions to ask your eye-care professional.

Understanding Vision Therapy: The Basics
Vision therapy is a supervised program of exercises for how the two eyes team up and focus, prescribed after an exam. It does not correct refractive errors such as nearsightedness; glasses do that.
Key Features of Vision Therapy:
- Prescribed: Only after a diagnosis by an eye-care professional.
- Office and Home: Weekly visits plus prescribed home practice, often with lenses, prisms or computer activities.
- Not a Glasses Replacement: It does not reduce the need for glasses.
What the Research Shows
The research is uneven. The strongest studies are randomized trials in children with convergence insufficiency. Claims about learning, reading and general eyesight are not supported.
What Research Says
| Study/Source | Findings |
| National Eye Institute (CITT-ART trial) | Office-based vision therapy improved convergence insufficiency symptoms, but did not improve children’s reading skills. See also the original trial (CITT, 2008). https://www.nei.nih.gov/about/news-and-events/news/treatment-common-vision-disorder-does-not-improve-childrens-reading-skills |
| The Bates method (proposed in 1920) | Often confused with vision therapy; not supported by evidence (AAO). Historical source: https://www.google.am/books/edition/The_Cure_of_Imperfect_Sight_by_Treatment/mWbA-Gz_YBgC?hl=en&gbpv=1&printsec=frontcover |
| AAP, AAO and partners (Pediatrics, 2011) | Do not endorse vision therapy as a treatment for dyslexia or learning disabilities https://doi.org/10.1542/peds.2010-3670 |
1. Does Vision Therapy Really Help?
It depends on the condition:
Conditions and Evidence:
| Condition | Symptoms | Where Vision Therapy Stands |
| Lazy Eye (Amblyopia) | Poor vision in one eye | Mainly treated with glasses, patching or drops; therapy sometimes added |
| Crossed Eyes (Strabismus) | Misalignment of eyes | Depends on type; glasses, therapy or surgery |
| Convergence Insufficiency | Double vision or difficulty reading | Strongest evidence for office-based therapy |
| Eye Strain from Screens | Fatigue, headaches, blurry vision | Usually not needed; breaks and blinking help |
2. The Process: What to Expect
Vision therapy starts with a comprehensive evaluation to identify functional vision issues. The program is then customized with:
- In-Office Sessions: Guided by a trained optometrist.
- At-Home Exercises: As prescribed, between visits.
- Re-testing: Progress is measured by the professional.
3. When It Is Worth Considering
Ask about vision therapy if:
- You have been diagnosed with convergence insufficiency.
- Close work causes double vision or strain that doesn’t go away with rest.
- Your eye-care professional recommends it and can explain the evidence.
Pros and Cons of Vision Therapy
| Pros | Cons |
| Strong evidence for convergence insufficiency | Requires time and consistency |
| Supervised by a professional | Not always covered by insurance |
| Non-invasive | Weak evidence for many other uses |
What About Apps?
Apps are not vision therapy. VisionUp is a wellness app for everyday eye strain:
- Not a Treatment: It doesn’t diagnose or treat any condition.
- Not a Substitute: It doesn’t replace office-based therapy.
- For Comfort: Short relaxation breaks for tired eyes.
If you have a binocular vision problem, follow your eye-care professional’s plan.
Key Takeaways:
- Vision therapy has strong evidence for convergence insufficiency, mostly in children.
- It did not improve reading in an NEI-funded trial and is not endorsed for learning disabilities.
- Apps, including VisionUp, are not vision therapy.
FAQs
1. Does vision therapy work for adults?
Adults with convergence insufficiency may be offered it; the evidence in adults is smaller than in children.
2. How long does vision therapy take?
Usually several months of weekly visits; your provider will estimate it.
3. Is vision therapy a replacement for glasses?
No, it complements glasses by addressing functional issues, not clarity.
4. What conditions does vision therapy treat?
Mainly convergence insufficiency, and as part of care for some cases of lazy eye and crossed eyes.
5. Are there alternatives to in-office therapy?
Some programs include remote check-ins, but the diagnosis and supervision come from an eye-care professional. Apps are not vision therapy.
