binocular vision The use of two eyes, set a small distance apart in the head and aligned approximately parallel, to view a single object. Owing to parallax, the images in the two eyes are slightly different, which enables the observer to perceive what is seen in three dimensions and so to judge distance, size, and shape. Only humans and some other higher animals possess binocular vision.
