The sensory receptors of the retina are called rods and cones. Rods, which are the more numerous receptor type, provide vision in dim light, but vision coming from the rods is poor in quality. Cones are responsible for vision in bright light and provide great visual acuity.

At the center of the retina is a small area called the fovea, which provides the sharpest vision of the entire retina. The fovea contains many cones but no rods. The layers of the retina come together to form the optic nerve, a bundle of fibers that transmits visual information from the eyes to the brain.
