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

  • Eyestrain
  • Headaches
  • 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.
