ABSTRACT:
A visual function tester with binocular vision testing capabilities is disclosed, which includes a video display monitor and optical means, such as stereo vision glasses, to control the patient's viewing of the display. The opening and closing of the apertures of the glasses is synchronized to the display of a variety of visual acuity images. Certain images are made visible to each eye but not visible to the other, and certain images are displayed such that they appear out of the plane of the images. Methods for use of the apparatus are also disclosed.
