Abstract: A head-mounting device includes an elongate strip-like body having an arcuate configuration suitable to fit over a wearer's head and extending from the forehead to the back of the head whereby front and rear ends of the strip-like body are located adjacent the forehead and the back of the head. Two side-wings extend from opposite edges of the strip-like body in substantially opposite directions for engaging sides of the wearer's head. An electrically powered eye training device is attached to the front end of the strip-like body whereby the eye training device is substantially located in front of the wearer's eyes. A controller is attached to the rear end of the strip-like body and is electrically connected to the electrically powered eye training device for controlling the operation of the eye training device.

Abstract: A vision training device includes a fixed frame positionable in front of a wearer's face. The fixed frame defines two windows corresponding in position to the eyes of the wearer, through which light passes. An optic system includes a prism lens, which may have fixed power or variable power by changing shapes thereof. The prism lens is mounted to the fixed frame and is movable between first and second positions, wherein in the first position, light is allowed to pass in a first state with which the eyes are adducted, and in the second position, light is allowed to pass in a second state with which the eyes are abducted. A transmission system is coupled to and selectively drives the prism lens between the first and second positions. Thus, by repeatedly and cyclically moving the prism lens between the first and second positions, the eyes are forced to change between adduction and abduction thereby realizing training of vision.
