Symptoms

Not everyone with convergence insufficiency has signs and symptoms. Signs and symptoms occur while you're reading or doing other close work and might include:

• Tired, sore or uncomfortable eyes (eyestrain)
• Headaches
• Difficulty reading — words seem to float on the page, you lose your place or you read slowly — which might cause you to avoid reading or not complete schoolwork
• Double vision (diplopia)
• Difficulty concentrating
• Squinting, rubbing or closing one eye

When to see a doctor

If you or your child has symptoms of convergence insufficiency or problems reading, consult an eye care professional — an ophthalmologist or an optometrist.
