Symptoms
By Mayo Clinic staffNot everyone with convergence insufficiency experiences symptoms. Signs and symptoms occur while you're reading or doing other close work and may include:
- Tired, sore or uncomfortable eyes (eyestrain)
- Headaches
- Blurred vision
- Difficulty reading — words seem to float on the page, you lose your place or you read slowly
- Double vision
- Difficulty concentrating
- A "pulling" feeling around your eyes
- Sleepiness
- Squinting, rubbing or closing one eye
When to see a doctor
If you or your child experiences 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 assist the eye care professional in evaluating and treating convergence insufficiency.
