Unlike most lizards, this gecko does not have eyelids. What special adaptations does it have to deal with this?

Answer:

Most geckos do not have eyelids, which means that their eyes are always open. To protect the delicate eye, it is covered by a transparent scale called a Brille, which acts much like an eye goggle. Snakes also have a brille to protect their eyes. The brille is shed when the animal sheds its skin. In between sheds, geckos clean the brille by licking it with their long, flexible tongues.
