Some animals have a third eye lid, Including some lizards and camels. The main reason for this is to offer the eye extra protection from sand and dust. As many animals live in environments where it is a true risk of being blinded by constant sand clouds, and the third eyelid, which usually goes across the way offers the eye slightly more protection.
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.
One eye lid is stronger than the other eye lid. The bigger the fold the weaker your eye lid is.
