Skinks are one of the largest groups of lizards. As they burrow, skinks close their eyes to keep the dirt out. They can see while they do this because of their transparent eyelids.

Oriental Bay Owl can see with its eyes closed because of its big black eyes and white eyelids. Their white eyelids have small slits that essentially let this species of owl see with its eyes closed.
Chameleons can see with their eyes closed because of a small hole in the center of their eyelid. Their eyes can also move independently of one another, making it a lot easier for chameleons to keep an eye on their surroundings and hunt for prey.

Did you know that snakes keep their eyes closed all of the time? Instead of having movable eyelids, snakes have a single eyelid that is semi-transparent. This is often referred to as a snake’s “spectacles”.

A camel’s third eyelid is called a nictitating membrane. It is thin and transparent, so it keeps out dirt and dust when sand blows around in the desert but doesn’t stop the camel from being able to see.

Like camels, frogs have a nictitating membrane. Instead of using theirs on land, however, frogs use this thin, transparent eyelid to keep debris out of their eyes when swimming around in the pond or lake.

The octopus is also unique in the way that it uses its eyes to help camouflage itself in its environment. It can constrict and dilate its pupil as needed to blend into the environment.

While the platypus can’t technically see with its eyes shut, it does close its eyes while on the hunt. In fact, when a platypus dives underwater, it has muscles that close its eyes and ears to keep water and debris out.
