Vision therapy has been around for over 80 years, but unfortunately not enough doctors provide quality programs of vision therapy. Optometrists learn about vision therapy in school. However, putting it into a practice setting is a very different thing. It takes a great deal of time, equipment, staff, and special training to provide the service. Fortunately, there are many optometrists and other professionals that are aware of the symptoms of binocular vision problems and refer for care when appropriate.
