Course notes for "Therapeutic Prism - Vision Training Workshop"
Dr. Jen Simonson & Staff

We used the idea that "Therapeutic" meant that you were challenging the visual system vs. using prism in a compensatory way.

The goal of these exercises is to use prism in order to improve sensory perception and oculomotor control.
