Not everyone with convergence insufficiency experiences symptoms. Signs and symptoms occur while you're reading or doing other close work and may include:
- Difficulty reading — words blur or seem to move on the page
- Double vision
- Difficulty concentrating
- Squinting or closing one eye
When to see a doctor
If you or your child experiences signs and symptoms of convergence insufficiency or has problems reading, consult an eye care professional, such as an ophthalmologist or an optometrist. A technician called an orthoptist may help with the evaluation and treatment.
