How does the snake retina differ from that of other vertebrates?

Snakes eyes differ from eyes of mammals or other vertebrates. Other vertebrates are able to focus a sharp image on he retina of their eyes, by using a special muscle to change the shape of the lens. In many snakes though these muscles are absent, therefore a snake cannot focus on a stationary object. They are however very sensitive to movement. Some snakes have excellent eye sight but they are very uncommon.
