A sense organ that acts as a photoreceptor capable of image formation. The eye of vertebrates is a specialized light-sensitive sensory structure that provides these animals with vision (the sense of sight). It is constructed along a basic anatomical pattern (Fig. 1) that, in the evolution and diversification of animals, has undergone a variety of structural and functional modifications associated with different ecologies and modes of living. Often compared with a camera, the vertebrate eye is conveniently described in terms of its wall, cavities, and lens.
