Not 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.
