Are there associated problems with vision in patients with convergence insufficiency?
Patients with convergence insufficiency usually have a normal range of refractive errors and good visual function. Testing for accommodative amplitude (the ability to focus each eye individually at near) is always performed by the specialist evaluating convergence. Rarely, this is also found to be weak. If both accommodation and convergence are weak, reading glasses, sometimes with prism added, may be a great advantage for these patients. It is very difficult to improve accommodation with exercises.
