except when the animal is becoming ready for ecdysis. At that time, it becomes cloudy
and is visible as a cover over the eye. When the snake moults, the brille is also
shed as part of its skin. The Brilles protect their eyes from dust and dirt and gives
them a 'glassy-eyed' blank appearance Snakes, flap-footed lizards, night lizards,
and some skinks have brilles. All geckos except those in the subfamily Eublepharinae
(eyelid geckos) possess brilles. Fish also have transparent eyelids called adipose
eyelids.;
