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.
Claims14
A method for testing binocular vision using a display comprising the steps of:
- alternately displaying images on the display at a frequency sufficient to maintain fusion;
- alternately blocking or permitting a patient's viewing of the display;
- and
- synchronizing the displaying of the alternating images with blocking or permitting the patient's viewing such that some images are visible only to the patient's left eye, some images are visible only to the patient's right eye, and some images may be visible to both of the patient's eyes.
