They used clear calcite crystals to form the lenses of their eyes. The visual fields of some such complex eyes largely overlap, to allow better depth perception (binocular vision), as in humans; and others are placed so as to minimize the overlap, such as in rabbits and chameleons. Rod cells are highly sensitive to light allowing them to respond in dim light and dark conditions, however, they cannot detect color.The retina has a static contrast ratio of around 100:1
In most vertebrates and some molluscs, the eye works by allowing light to enter it and project onto a light-sensitive panel of cells known as the retina at the rear of the eye, helps maintain the shape of the cornea and lens, and from the length of the eyeball.
