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.
1 the retina The retina is the inner layer of the eye. 2  It contains the light receptors, the rods and cones (and thus serves as the film of the eye). 3  The retina also has many interneurons that process the signals arising in the rods and cones before passing them back to the brain. This not only reduces the amount of light entering the eye but also improves its image-forming ability (as does stopping down the iris diaphragm of a camera). 2  the retina The retina is the inner layer of the eye. 3  It contains the light receptors, the rods and cones (and thus serves as the film of the eye).
