Eyes are organs of vision that detect light. Different kinds of light-sensitive organs are found in a variety of organisms. The simplest eyes do nothing but detect whether the surroundings are light or dark. The visual fields of some such complex eyes largely overlap, to allow better depth perception, binocular vision, as in humans.
