Monocular vision is
vision in which both
eyes are used separately. By using the eyes in this way, as opposed by
binocular vision, the
field of view is increased, while
depth perception is limited. The eyes of an animal with monocular vision are usually positioned on opposite sides of the animal's head, giving it the ability to see two objects at once. The word monocular comes from the
Greek root,
mono for one, and the
Latin root,
oculus for eye.
