I would recommend that those who desire to try vision therapy to remedy their vision problems seek out an optometrist or ophthalmologist skilled in the diagnosis and treatment of vision disorders and practicing vision therapy on a regular basis. There are a number of specific vision system problems that have been shown to respond to therapy. Click on the links to go there. This, generally, consists of plus powered lenses for near vision tasks, often incorporated in eyeglasses as bifocal lenses. There are exercises that help the eye muscles to more appropriately respond to these tasks.
Hyperopia is a condition whereby the eye is deficient in focal power.
The muscles inside the eye can be strengthened to exert a greater force on the crystalline lens and cause a greater degree of focusing, overcoming the hyperopic deficit. With the exception of low degrees of hyperopia, exercises are generally not appropriate for this vision condition. This optical condition causes a distortion of the image and is caused by an unevenly curved cornea or crystalline lens and, more rarely, a retina which is uneven or lens which is suspended off axis. Thereby canceling each other. But not always.
