Three eyelids for protection

Camels have three eyelids. They have upper and lower eyelids that have eyelashes to shield the eyes from sand. In addition, camels have a third eyelid, which is thin like a transparent membrane. It opens sideways, from both sides, like a shutter. Camels can see through this third eyelid during sandstorms.
