Vision therapy is the physical therapy given to patient who is diagnosed to have binocular anomalies The goal of vision therapy is to optimize the visual system, and areas of the brain that control vision, visual efficiency, visual perception and other vision-related functions. By treating the entire visual system, vision therapy aims to change reflexive (automatic) behaviours to produce a lasting cure. Vision therapy can treat vision problems that interfere with efficient reading among schoolchildren. It provides treatment for amblyopia (lazy eye), learning related vision problems, traumatic/acquired brain injuries. It also can help reduce eyestrain and other symptoms of computer vision syndrome experienced by many children and adults that cannot be treated successfully with eyeglasses, contact lenses and/or surgery alone, and help people achieve clear, comfortable binocular vision.
