This is called the third eye lid. It will sweep the eye from time to time to clean it. It is also called a nictating membrane.
The tough, transparent cover of the eye is called the cornea. It helps to protect the eye and refracts light that enters the eye to help focus it on the retina.

Nope - if they need to 'clean' their eyeballs - they use their tongue to lick the surface. Crested geckos have a clear membrane covering the eye, this membrane is a clear, transparent eye contact more or less. it stops dirt, oxygen, water, substrates etc.. from entering the eye. when something external touches the membrane, they will lick their eye in order to remove anything. The Crested geckos come from the Diplodactylinae subfamily under the Genera Rhacodactylus. Geckos of the Eublepharinae Subfamily are known as "eye lid" geckos all have eye lids. These consist of the: Leopard gecko (E. macularius), the fat tailed gecko (E. Hemitheconyx) etc.. When sleeping, resting, swallowing, and of course blink, their eyelids will close.
The front clear surface of the eye is called the cornea. It protects the covering of the eye and helps to focus light.
The clear transparent protective coating over the front part of the eye is called the cornea. It is responsible for focusing light into the eye and protecting the eye from dust and other particles.
