Why do camels have three eyelids?
To protect their eyes, camels have long eye lashes that catch most of the sand. If some sand gets into an eye, a camel has a special third eyelid to get it out. Like a windshield wiper on a car, this extra eyelid moves from side to side and wipes the sand away. The eyelid is very thin, so a camel can see through it. In sandstorms, camels often close their extra eyelids and keep walking. You might say that a camel can find its way through a sandstore with its eyes closed.

In fact, many animals have this, including many fish, amphibians, reptiles, and birds. In many mammals, it is reduced, although mammals like polar bears, camels, and seals have full nictitating membranes. Cats and dogs have 3rd eyelids that are modified nictitating membranes. Humans only have two eyelids (the upper and lower eyelid) but the Plica Semilunaris is a vestigial remnant of the nictitating membrane (meaning the structure remains partially but doesn’t perform the same function).
