What is Vision Therapy?

* Vision therapy (visual training, vision training) is an individualized supervised treatment program designed to correct visual-motor and/or perceptual-cognitive deficiencies

Why Vision Therapy?

* Behavioral Optometrists believe that vision is a learned skill; Vision plays the largest role in learning.
