As with other reptiles, snakes have a yellow filter that absorbs ultraviolet light and protects the eyes. Snakes use their tongues to detect smells to find food or stay away from enemies. Many adult tiger snakes have had their eyes destroyed, apparently during nest defence, by silver gulls (Larus novaehollandiae). Alternative Titles: Typhlopoidea, scolecophidian snake Blind snake, (superfamily Typhlopoidea), any of several nonvenomous snakes characterized by degenerate eyes that lie beneath opaque head scales.

Male snakes have a pair of sex organs called hemipenis and these extend and release the sperm into the female snake.

In the place of the eyelids, there is a clear membrane cover at the corneas and it is called brilles or spectacles. There is a cobra, in which the holes are not at the tips of the teeth, but on their front surface. Most snakes focus by moving the lens back and forth in relation to the retina, while in the other amniote groups, the lens is stretched. Some lizards are legless and look like snakes, however, most lizards have eyelids, and snakes do not. Crocodiles see well during the day and may even have color vision, plus the eyes have a vertical, cat-like pupil that also gives them excellent night vision. Another effect in humans and other animals that may resemble eyeshine is leukocoria, which is a white shine indicative of abnormalities such as cataracts and cancers..
