The gnat has nearly one hundred
                 eyes. As compound eyes, these
                 are placed on the top of its head.
                 In the picture above, the cross-
                 sections of three of these eyes
                 are shown. On the right, we see
                 how the image of an object is
                 transmitted to the brain from
                 the eye.
