The fovea centralis is a small, central pit composed of closely packed cones in the eye. A schematic section through the human eye with a schematic enlargement of the retina. The main function of the macula is to provide sharp, clear, straight-ahead vision. Cones are concentrated near the fovea, responsible for color. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. The proper function of the eye depends on its ability to receive and process energy from light in the environment, produce action potentials in specialized nerve cells, and relay those potentials through the optic nerve (cranial nerve II) to the brain.
