Binocular Vision Testing

Binocular vision refers to both eyes working together as a a coordinated team. Each eye takes a "picture" and the two images are sent to the brain to merge. With normal healthy eyes the picture appears three-dimensional (stereo-vision) and gives you depth perception. If the image is received from only one eye, or if one image is much poorer quality, the necessary two reference points are absent and binocular depth perception is altered.

Several simple tests can evaluate binocular vision and depth perception. One of the most commonly used is the Stereo Fly Test. Polarized vectograph plates are viewed through polarized glasses. The images appear to raise up off the page in 3D if stereo vision is present.
