Document Summary
80% of the information that you get from the world comes through your visual system. 70% of the sensory receptors in the whole body are in the retinas. The stimulus for vision is electromagnetic energy, specifically the visible spectrum. The function of the eye is to focus this energy, transduce it into a neuronal signal, then to start processing this signal. There are many different types of eyes. Prey animals have eyes located on the sides of their head so as to maximize field of. It matters where the eyes are located in the head view (fov) Rabbit - narrow binocular vision in front and behind head; useful for running through field/forest and also to avoid predators. Predators have centrally positioned eyes so as to maximize binocular depth perception, large overlap between eyes. Blind spot behind predator, can"t see behind head. Binocular vision in primates helps us to use tools. Eyes very close together relative to other species.
