Retina: The retina is the nerve layer that lines the back of the eye, senses light, and creates impulses that travel through the optic nerve to the brain. There is a small area, called the macula, in the retina that contains special light-sensitive cells. The macula allows us to see fine details clearly.
eye. 1. The organ of the body with which an animal is able to see or sense light. In vertebrate animals, the eye occurs as one of a pair, each consisting of a spherical structure that is filled with fluid. Incoming light is refracted by the cornea and transmitted through the pupil to the lens, which focuses the image onto the retina. See more at compound eye, eyespot.
