Eyelids are protective coverings over an animal’s eyes. Camels actually have three sets of eyelids!! Why? It is all because of the environment they live in. Camels live in the desert, which means that there is a lot of sand blowing around. To protect it’s eyes, the camel has extra sets of see-through eyelids and one opaque eyelid. This adaptation helps camels see during a sandstorm.
