Why Do Geckos Get Eye Caps?

Geckos are fascinating creatures with unique abilities, such as their ability to climb walls and ceilings effortlessly. One of the most intriguing aspects of geckos is their ability to shed their eye caps. But why do they do this, and what purpose does it serve?

Eye caps are a protective layer of skin that covers a gecko’s eyes. These caps are shed periodically, and the process is essential for maintaining the gecko’s vision and health. In this article, we will explore the fascinating world of geckos and discover why they get eye caps. So, let’s dive in and unravel the mystery of this remarkable reptile!

Why Do Geckos Get Eye Caps?

Geckos are fascinating creatures that have unique features, including the ability to regenerate their tails and the presence of adhesive pads on their feet. However, one of the most interesting aspects of geckos is the presence of eye caps. Eye caps are thin, transparent scales that cover the eyes of geckos. You may wonder why geckos have eye caps and what their purpose is. In this article, we will explore the reasons behind this unique feature of geckos.

What are Eye Caps?

Eye caps, also known as spectacle or brille, are transparent scales that cover the eyes of geckos. They are made of keratin, the same material that makes up human hair and nails. Eye caps are attached to the skin around the eyes and are shed along with the skin during the molting process.

Eye caps are found in all types of geckos, from small species like dwarf geckos to larger ones like tokay geckos. They vary in size and shape, depending on the species and the size of the gecko. Some geckos have round eye caps, while others have rectangular or triangular ones.

Reasons Behind Eye Caps

There are several reasons why geckos have eye caps. One of the main reasons is protection. Eye caps act as a shield for the eyes, protecting them from scratches, dust, and other debris. Geckos are active climbers and hunters, and their eyes are vulnerable to damage. Eye caps help to keep their eyes safe and healthy.

Another reason for eye caps is to help with shedding. Geckos shed their skin regularly, and the eye caps also shed along with the skin. This ensures that the eyes are not obstructed during the shedding process. The eye caps also help to keep the skin around the eyes moist, which is important for the shedding process.

Benefits of Eye Caps

Eye caps provide several benefits to geckos. Firstly, they protect the eyes from injury, which is essential for their survival in the wild. Secondly, they help with the shedding process, which is crucial for maintaining healthy skin. Thirdly, eye caps may also help geckos to see better. The transparent nature of the eye caps allows light to pass through them, enhancing the geckos’ vision.

Eye Caps Vs Eyelids

Unlike most animals, geckos do not have eyelids. Instead, they have eye caps that serve the same purpose as eyelids. Eyelids are movable structures that cover the eyes and protect them from damage and debris. However, eyelids can also obstruct the vision, which is not ideal for an animal like a gecko, which relies heavily on its vision. Eye caps provide the same protection as eyelids but without hindering the gecko’s vision.


In conclusion, eye caps are a unique feature in geckos that serve several purposes. They protect the eyes from damage, help with shedding, and may even enhance the gecko’s vision. Eye caps are just one of the many fascinating adaptations that geckos have evolved to survive in their environment.

Frequently Asked Questions

Why do geckos get eye caps?

Geckos belong to the lizard family and are known for their unique characteristics, including the ability to climb walls and ceilings due to their specialized toe pads. One of the other interesting features of geckos is that they shed their skin, including the skin covering their eyes, called eye caps. Here are some frequently asked questions about why geckos get eye caps:

What are eye caps?

Eye caps are the transparent skin that covers a gecko’s eyes. They are made of a thin layer of skin that protects the eyes from dust and debris. The eye caps are connected to the rest of the skin on the gecko’s body, and when the gecko sheds its skin, the eye caps come off too.

Why do geckos get eye caps?

Geckos get eye caps because they shed their skin. The eye caps protect the gecko’s eyes from debris and other harmful substances while the gecko is shedding its skin. Without the eye caps, the gecko’s eyes would be exposed and vulnerable to injury during the shedding process.

How often do geckos shed their skin?

Geckos shed their skin regularly throughout their lives. The frequency of shedding depends on the species, age, and health of the gecko. Younger geckos shed their skin more often than older geckos, and sick or stressed geckos may shed more frequently.

Is it normal for a gecko to eat its eye caps?

Yes, it is normal for a gecko to eat its eye caps after shedding. The eye caps are a good source of nutrition for the gecko, as they contain protein and other nutrients. Eating the eye caps also helps keep the gecko’s environment clean, as it eliminates the need for the owner to clean up the discarded eye caps.

What happens if a gecko does not shed its eye caps?

If a gecko does not shed its eye caps, it can lead to serious health problems. The eye caps can become stuck on the gecko’s eyes, obstructing its vision and causing irritation and infection. If the eye caps are not removed, it can lead to permanent damage to the gecko’s eyesight. Therefore, it is important to ensure that your gecko sheds its skin properly and that the eye caps are removed if necessary.

In conclusion, geckos are fascinating animals that have evolved unique adaptations to help them survive in their environments. One of these adaptations is the shedding of their eye caps. While it may seem strange to us humans, this process is crucial for the health and well-being of geckos.

By shedding their eye caps, geckos are able to maintain clear vision and protect their eyes from debris and infection. This adaptation has helped geckos become successful hunters and escape predators in the wild.

Overall, the shedding of eye caps is just one of the many incredible adaptations that geckos have developed over time. As we continue to learn more about these fascinating creatures, we can gain a greater appreciation for the complexity and diversity of the natural world.
