The center of the retina is the macula . This region is responsible for most of the eye's ability to distinguish small details and color. The rest of the retina is good at distinguishing movement. Rods are cells which help the brain interpret images seen in low light. There are a few in the macula, but most are located around the periphery of the retina.
Cones are cells which distinguish color.
They are located only in the macula. They do not function well in environments with low lighting. It doesn't go straight there. A short way from the eyes, each optic nerve splits in half. The parts that carry the information from the left halves of the two retinas join up, as do the parts that carry the information from the right halves.
