D
The innermost layer of the eyeball, or the retina, is an extension of the optic nerve, which lines the inside of the globe and receives light impulses to be transmitted to the occipital lobe of the brain. In the temporal area of the retina, the tiny, darker macula, with the fovea centralis at its center, contains a high concentration of cones. Cones are necessary for color vision, reading ability, and other tasks requiring fine visual discrimination. The fovea is the area of sharpest vision.
