Which conditions is vision therapy used for? Vision therapy is a clinical treatment by eye-care professionals for problems with how the eyes team and focus. Its strongest evidence is for convergence insufficiency. It is also part of care for some cases of lazy eye and eye misalignment, while the evidence for reading and learning problems is weak. VisionUp is a wellness app, not vision therapy.
Imagine struggling to focus on a page, read without losing your place, or even catch a ball during a game. These challenges can be frustrating, and they have many possible causes. An eye exam is the place to start.
In this article, we look at five conditions people often associate with vision therapy, what the evidence says for each, and what to ask your eye-care professional.
5 Conditions and What the Evidence Says
1. Amblyopia (Lazy Eye)
Amblyopia occurs when vision in one eye doesn’t develop properly, usually in childhood. The main treatments, prescribed by an eye doctor, are glasses, patching or eye drops; some clinicians add supervised therapy.

- Symptoms: Blurred vision in one eye, poor depth perception.
- Who treats it: An eye doctor, ideally early in childhood.
2. Strabismus (Eye Misalignment)
Strabismus, or crossed eyes, occurs when the eyes don’t align properly. Depending on the type, an eye doctor may prescribe glasses, therapy or surgery.
- Symptoms: Misaligned eyes, difficulty focusing.
- Who treats it: An eye doctor; the right option depends on the type.
3. Convergence Insufficiency
This condition makes it hard to focus on close objects, causing headaches and reading fatigue. Here the evidence is strongest: an NEI-funded trial (CITT, 2008) found office-based vision therapy worked better than home exercises alone in children.
- Symptoms: Eye strain, double vision, headaches.
- Who treats it: An optometrist or ophthalmologist, with office-based therapy and prescribed home practice.
4. Visual Processing Disorders
People with this condition struggle to interpret visual information, even if their eyesight is fine. These need a full assessment; vision therapy for them is debated and evidence is limited.
- Symptoms: Difficulty recognizing shapes, letters, or spatial relationships.
- Who to see: An eye doctor plus, often, an educational or developmental specialist.
5. Reading and Learning Difficulties
Children who struggle to read should have an eye exam, since glasses may help. But pediatric and ophthalmology societies do not endorse vision therapy as a treatment for dyslexia or learning disabilities.
- Symptoms: Losing place while reading, slow reading speed, frustration.
- Who to see: An eye doctor to rule out vision problems, and the school or a learning specialist for reading support.
Useful to know: The Bates method, from Dr. William H. Bates’s book “The Cure of Imperfect Sight by Treatment Without Glasses“, was proposed in 1920 and is sometimes confused with vision therapy. It is a different idea, that relaxation exercises can replace glasses, and it is not supported by evidence (AAO).
Vision Therapy Conditions at a Glance
| Condition | Common Symptoms | What the Evidence Says |
| Amblyopia (Lazy Eye) | Blurred vision, poor depth perception | Treated mainly with glasses, patching or drops |
| Strabismus (Misaligned Eyes) | Misalignment, double vision | Depends on type: glasses, therapy or surgery |
| Convergence Insufficiency | Headaches, eye strain | Strongest evidence for office-based therapy |
| Visual Processing Disorder | Trouble recognizing shapes, letters | Limited evidence |
| Reading Difficulties | Slow reading, losing place | Not endorsed as a learning-disability treatment |
Pros and Cons of Vision Therapy
Pros
- Non-Invasive: Uses exercises, not surgery.
- Supervised: Designed and adjusted by a professional.
- Evidence for CI: Well studied for convergence insufficiency.
- Specific: Targets a diagnosed problem rather than general eyesight.
Cons
- Time Commitment: Requires consistent effort.
- Costly: Several months of office visits; insurance coverage varies.
- Limited Evidence: For many uses beyond convergence insufficiency.
At Home: What You Can and Can’t Do
Vision therapy isn’t a do-it-yourself treatment. Here is what that means in practice:
1. Apps Are Not Vision Therapy
No app replaces a diagnosis and a supervised program. VisionUp is a wellness app for everyday eye strain and does not treat lazy eye, convergence insufficiency or any other condition.
2. Home Practice, Only as Prescribed
- Pencil Push-Ups: Sometimes prescribed for convergence insufficiency; on their own they did worse than office-based therapy in the CITT trial.
- Brock String: A tool clinicians may include in a home program.
- Palming: A relaxing break for tired eyes; it is not therapy.
3. Simple Adjustments
- Take frequent breaks during screen time.
- Use proper lighting to reduce eye strain.
- Encourage outdoor play for children.
How to Know if Vision Therapy Is Right for You
Ask yourself these questions:
- Do you or your child struggle with reading, focus, or coordination?
- Do you get double vision or eye strain with close work?
- Has an eye-care professional diagnosed a binocular vision problem?
If so, ask your eye-care professional whether vision therapy is indicated, what the evidence is for your diagnosis, and what it will cost.
Conclusion
Vision therapy is a clinical treatment with good evidence for convergence insufficiency and a role in some other eye-teaming problems. It is not a treatment for learning disabilities, and it isn’t something an app can provide. Start with an eye exam.
Key Takeaways

FAQs
- What conditions does vision therapy treat?
Mainly convergence insufficiency, plus some cases of lazy eye and misalignment as part of a wider plan. It is not endorsed for learning disabilities. - Can adults benefit from vision therapy?
Adults with convergence insufficiency may be offered it; ask your eye-care professional what the evidence is for your case. - Can an app replace in-office therapy?
No. Apps, including VisionUp, are not vision therapy. - How long does vision therapy take to work?
Programs usually run for a few months; your eye-care professional will advise. - Do I still need glasses with vision therapy?
Yes, if you have a refractive error. Exercises don’t replace glasses.
