Abstract
Abstract An eye training device for treating one or more visual disorders in a patient, which displays two images visually superimposable into a single image and optically conducts one of the images to a right eye viewing port and the other image to a left eye viewing port. The device further includes an assembly for modifying the perception of one or both images by the patient to differ from the perception required for normal viewing of the images to exercise corresponding one or both eyes of the patient. At least one of the first and second images has a first image element whose location is changeble relative to the other image elements, and the device further includes a mechanism which is operable by the patient to move the first image element while the patient views through the viewing ports.
