The lens concentrates on light through the transparent humor, a transparent gel-like material that permeates the back of the eye and controls the retina. The retina sustains the image that the cornea concentrates through the eye's inner lens and converts this image into electrical vibrations that are transported by the optic nerve to the brain.
