The retina is the interior lining of the eye that contains millions of light–sensitive nerve endings called “rods” and “cones,” most of which are concentrated at the back of the eye. The retina transmits nerve impulses through the optic nerve at the back of the eye to the brain. The central portion of the retina is called the macula and provides central vision. In the center of the macula is the fovea, which provides the sharpest vision. Outside of the macula is the peripheral retina which provides peripheral vision
The vitreous is a clear, gel–like material that fills the eyeball and produces the eye’s spheroid shape.
