Vision exercise device
Abstract:
An embodiment of the disclosure consists of a rectangular lightweight rigid handled frame, four adjustable telescoping foldout locking legs with protective feet, a rear-facing mirror, a pair of forward-facing mirrors, an eleven-light light source, and a control panel. The rear-facing mirror is connected to the frame and is adjustable about a horizontal axis to form a vertical angle in order to facilitate the reflections from the light source back and forth between the rear-facing mirror and the pair of forward-facing mirrors. The pair of forward-facing mirrors are connected to the frame, are spaced apart to form the porthole, and are adjustable on both a vertical and horizontal axis in order to form the vertical angle and the rotational angle needed to facilitate the reflections from the light source back and forth between the rear-facing mirror and at least one of the pair of forward-facing mirrors.
