Eye

The human eyeball is somewhat like a camera, not in the way it looks, but in the way that it works. Both have a lens through which light passes. In the eye, the external image is focussed on the retina, which is like the film of a camera. The eyeball has three external layers of tissue, which help to protect the eye and keep the eyeball's shape. The outer layer is a supporting layer which is known as the sclera. MORE! [CG] {NR}
