Convergence Insufficiency (CI) is the leading cause of eyestrain, blurred vision, double vision (diplopia), and/or headaches.
- Convergence insufficiency is a common near vision problem, 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 paediatrician’s eye tests, school screenings or basic eye exams.
- 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)
- Home-based pencil push ups therapy appears to be the most commonly prescribed treatment, but scientific studies have shown that this treatment is not always ineffective
- Eye surgery is rarely, if ever, recommended.
While clinical results show that Convergence Insufficiency can be treated at any age, current scientific research has been completed on the paediatric and young adult populations only.
Silverman Opticians offer a Visual & Clinical eye tracking assessment where we can assess and track if the patient has convergence insufficiency.
What happens after a Visual & Clinical eye tracking assessment?
There are 5 possible outcomes of an assessment.
- No action.
- Specially prescribed reading spectacles, possibly in the form of bifocals, or including prism lenses, to maximise visual efficiency for near tasks
- A programme of vision therapy activities to address any weaknesses. An idea as to the length of the programme, and the frequency of appointments (weekly, fortnightly or monthly)
- A combination of 2&3
- A referral to another practitioner or discipline where appropriate
