The Eye
Your two eyes provide an incredibly detailed, constantly updated, three-dimensional, colour view of the world. Light rays enter the eye through the cornea, a domed window at the front. They are detected by the retina, a layer of light-sensitive cells. The retina is not much larger than a postage stamp-and even thinner. From the pattern of light rays, the eye generates patterns of nerve signals and sends them to your brain. The parts of your brain specialized for dealing with sight, the visual centres analyse all the information coming in from the eyes. It is your brain that tells you what kinds of shapes and forms, shades and colours, positions and movements you are looking at.
