Best Answer

the crested gecko has a clear membrane called a brine. This brine allows them to have their eyes fixated at all times. Living in a tropical envoirenment, the crested gecko is exposed to rain daily and the rain is able to slide off the brine. This also allows the gecko to have a view of it's surroundings at all times. Because the crested gecko is an semi aboreal species, they do not need to dig into soil often. Most gecko species with eyelids are able to close their eyes while burrowing.

How do you know if your gecko is dead or sleeping?

Im pretty sure, you just have to hold him for awhile. i pet mine on the head while he lies in my hand, and when i stop, and he doesnt look around, i figure he must be sleeping...or i rub overtop of his eye (where his eyelid WOULD start) and he doesnt stick them in his head. the question would be sooooo much easier to figure out if they had eyelids lol :(

How come the crested gecko has no eyelids?

In my theory it may be something to do with being nocturnal; however as an alternative they lick their eyesThe crested gecko (R.Cilatus) is a nocturnal species and have no eyelids, as the leopard gecko (e.Macularis) is a nocturnal species and do have eyelids. In every environment is a food chain, Geckos are not so high on the charts and almost anything can eat an animal that weighs 30-80Grams and only reach 9". Being an arboreal species living 3-12Feet of the ground, any predator over top can quickly snatch a crestie with ease. Crested geckos (along with all of their closely related cousin's [R.leachianus, R.Sarasinourim, R.auriculatus, R.chahoua etc.]) are animals with extremely weak jaws (in comparisson to other gecko species), robust body's, and an anchor as a tail, must be aware of their surrounding's. Their eyes being fixed open at all times allows them to do so. Most species of gecko with eyelids, are ground dwellers and usually burrow within the dirt. Having the ability to close their eyes keeps dirt, sand and mud from entering the eyes.
