What is it called when eyes are on the side of the head?
Monocular vision is vision in which both eyes are used separately. By using the eyes in this way the field of view is increased, while depth perception is limited. The eyes of an animal with monocular vision are positioned on opposite sides of the animal’s head, giving it the ability to see two objects at once.
