Fields of View

Dogs and cats can see about 150° around from their nose. The horse can see about 350° around because their eyes are positioned to the side of the head. This makes horses better able to watch for potential predators. Humans have a smaller field because our eyes are directed straight ahead. Binocular vision (stereo vision) occurs where the visual field of the two eyes overlaps. In the binocular field depth perception is improved and vision is better. Dogs and cats have some binocular vision but not as much as people. In dogs and cats the binocular field is 85°, in horses it is around 65°, and in people it is around 120°.
