Do Crested Geckos Have Eyelids And How Do They Sleep?

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. Lizards need to feel calm and find a place to hide when they sense threat or want to rest and sleep. In this paragraph, I did more research back on their sleep and eye features. So, do crested geckos have eyelids, and how do they sleep?

Characteristics & Change of Eyes during Sleep

Very often, I watch my pet. I was especially concerned about the question of changing eyes during sleep. Consequently, such creatures are born without eyelids. But geckos also don’t close their eyes when sleeping. So, I decided to compare and explore such features.

Of course, these reptiles are interesting in their characteristics, behavior, and structure. If you love and have such a pet at home for a long time, then you probably already understand how their eyes behave in different periods – sleep, rest, and activity. However, people who have recently bought such a lizard must learn a variety of info.

So, how to tell if a crested gecko is sleeping? I made a chart with several characteristics. I believe that with the help of such features, you’ll distinguish and understand.

Lowered (pressed) crests
  • Crests pressed to the body.
  • The protrusions seem to fall on the body.
Sunken, hidden eyes
  • The eyes are sunken and hidden inside the skull.
  • Reptiles look frowning and dissatisfied.
Narrowed pupils
  • Pupils completely change shape.
  • They become very narrow during sleep.

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?

Do Crested Geckos Sleep With Their Eyes Open

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.


Are Crested Geckos Nocturnal or Crepuscular?

They are active and energetic in the dark, at dusk, night, and dawn. These reptiles eat, hunt, and run around the terrarium at that time. And they sleep or sit quietly somewhere in an inconspicuous corner in daylight. Based on this, such pets are nocturnal and crepuscular.

Do Crested Geckos Blink?

Most lizards, including the species we are talking about, do not have eyelids. That way, there can be no question of blinking. There is a specialized film (scales) on the eye, and creatures lick the dust with the big long tongue, specially adapted for such work.

Do Crested Geckos Have Good Eyesight?

Yes, they see substantial and have excellent eyesight. Even at night, their sight is unsurpassed. Lizards hunt their prey and eat. They even distinguish some colors, certainly not like people, but quite well.



So, as you learned, geckos are extremely interesting and unique reptiles. They have many distinctive features. Consequently, how do geckos sleep without eyelids? What is the protection of their eyes? I think you have already known the responses to that and other issues. Therefore, I believe that owners should respect their structure and their nature. Try to support all common habits of your pet.
