The optic disc is where blood vessels enter the eye and the axons forming the optic nerve leave the eye. It is located medially on the retina. There are no receptor cells at the optic disc so it is a functional blind spot. The macula lutea is located on the retina directly posterior to the center of the lens. The macula lutea has more cones than rods. The fovea centralis appears as a small depression in the center of the macula lutea. It contains only cones, so it is the area of sharpest vision. The rest of the retina contains a mixture of rods and cones, which allows you to see the color of objects focused anywhere in your field of vision whether you are looking directly at the object or not.
