  • Interesting fact: An owl has three eyelids
    • n eyelid The cover of the eye; that portion of movable skin with which an animal covers the eyeball or uncovers it at pleasure. It serves the purposes of protecting and wiping the ball of the eye, as well as of moistening it by spreading the lacrymal fluid over its surface. Eyelids occur in mammals, birds, most reptiles, and Amphibia, not in Ophidia and true fishes. They are generally two in number, upper and lower, formed of ordinary skin and a layer of conjunctiva, stiffened or not with cartilage, and furnished with appropriate muscles, glands, etc.; they are technically called palpebræ. Some animals, as birds, have a third eyelid, the nictitating membrane, a fold of conjunctiva capable of being swept obliquely across the front of the eyeball; some mammals possess it imperfectly developed, as the horse. A similar structure defends the eye of some sharks, though seldom called eyelid. Serpents have no proper eyelids, because the cuticle continues unbroken over the eyeball. See cut under eye.
