upper and lower eyelids have eyelashes, which mechanically prevent sand from hitting the eye.
the third eyelid is a transparent membrane that blinks sideways. Ostensibly, in blasts of sandy wind this eyelid may be kept closed without significantly impairing the ability of the camel to see.

One clear one to see under water and another to completely close their eyes. They have one pair of eyes, with two pairs of eyelids: one regular pair, and an inner eyelid that is transparent called a nictitating membrane, used to protect their eyes when underwater. Sometimes it will be said that they have three eyelids, because you can count the regular eyelids as two, top and bottom, and the nictitating membrane as number three.
