What is Convergence Insufficiency (CI)?


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).1-48
  • 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.368
  • Eye surgery is rarely, if ever, recommended.12
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.
