ABSTRACT:
A binocular vision training device is described which includes a lighted enclosure having a pair of viewing ports through which a patient can view the interior of the enclosure, each eye being in registry with one of the ports. Within the enclosure, there are two stationary vertical posts oriented and aligned in a vertical plane bisecting the distance between the viewing ports, and a post movable in the same vertical plane back and forth from a position directly above one of the stationary posts to a position directly above the remaining stationary post. The movement of the latter post exercises critical muscle culture and the mental processes necessary for proper binocular perception of fine visual stimulus patterns.
