Every crested gecko is unique with different features and behavior but sleeping all day until dusk. They are energetic in the darkness because, in the natural environment, they try to hide from predators in the daytime. Therefore, the holders ought to ensure them with the same conditions.

So, do crested geckos have eyelids, and how do they sleep?

However, people who have recently bought such a lizard must learn a variety of info.

Features, Protection & Process of Sleep
The lizards have a lot of specific features in body structure that distinguish them from their relatives. The presence of certain protrusions above the eyes is a distinctive characteristic. They look like eyelashes, and their size in crested gecko is similar to humans. These protrusions don’t play any role in protecting the eyes from dust or dirt. Besides, there are two long stripes on the back that will extend the lashes along the body. Several issues concern many owners, and I’ll try to give you a logical and correct answer to them.
What Do Crested Geckos Have Instead of Eyelids?

Many owners have already remarked on the without eyelids. But how without them? There are other characteristics. They possess a transparent shell (membrane) on their eyes. That membrane looks like a glass film, scale, or oilcloth and serves to protect and acts as eyelids in humans. Besides, it keeps the eye moist.
Why do crested geckos lick their eyes?
As you understand, the eyes and the scale on it may cover with dust or become dry. In this case, the lizards somehow have to deal with such a problem. So, nature endowed them with a long tongue for such a duty. It copes perfectly with cleaning and moisturizing.
Do Crested Geckos Sleep With Their Eyes Open?
It is arduous for us, humans, to understand how it’s feasible to be constantly with our eyes open. However, these reptiles are created so that they have no eyelids or eyelashes. This way, you’ll think about how they can sleep. I know that it looks like they are watching. But their pupils, protrusions, and eyeball demonstrate that they are unresponsive. Lizards narrow their pupils as much as possible, and eyes seem to hide into the skull. Nevertheless, they respond to light, so you shouldn’t disturb your pet if you detect any signs of sleep.
When Do Crested Geckos Sleep?
Not every reptile monitors and adheres to the same hours of rest. Most of them sleep only in daylight, even for twelve hours. Nature created them as nocturnal creatures with the ability to hunt, eat and be energetic at night. Besides, the daytime for them is a time of rest.
