Convergence Insufficiency

Convergence Insufficiency (CI) is the leading cause of eyestrain, blurred vision, double vision (diplopia), and/or headaches.1

HIGHLIGHTS:

  • Convergence insufficiency is a common near vision problem that — due to recent scientific research — is gaining public recognition.
  • Convergence insufficiency disorder interferes with a person’s ability to see, read, learn, and work at near (close distances).
  • In the past, convergence insufficiency disorder has often gone undetected because testing is not included in (1) pediatrician’s eye tests; (2) school screenings; or (3) basic eye exams1.
  • A person can pass the 20/20 eye chart test and still have convergence insufficiency.
  • Treatments range from passive (prism lenses) to active (office-based vision therapy).1-4, 8
  • Scientific research by the National Eye Institute has proven that office-based vision therapy is the most successful treatment.8
  • Home-based pencil pushups therapy appears to be the most commonly prescribed treatment5, but scientific studies have shown that this treatment is ineffective.3, 6, 8
  • Eye surgery is rarely, if ever, recommended.1, 2
  • While clinical results show that Convergence Insufficiency can be treated at any age, current scientific research has been completed on the pediatric and young adult populations only.1, 2, 4, 8
