A nictitating membrane The nictitating membrane is the THIRD eyelid, the SECOND eyelid that you asked about is just that, the eyelid, just like in humans
The eyelid protects the front part of the eye. The eyelid is a piece of skin that is movable so that it can open and close. The eyelid also helps keep the eye moist. It does this by blinking. The eyelid also has great reflexes. If a ball or other object is coming towards the eye, the eyelid will quickly close to protect the eye. The eyelid will also close or squint when there is bright sunlight.
Yes, they do have eyelid, but not a human eyelid, they have special kind of eyelid which will let them see underwater and by the way I don't know the name of that kind of eye lid :P hope this answer help you.

the eyelid
No, the eyelid is not a bone. It is a thin fold of skin and muscle that covers and protects the eye.
Tears produced by the lacrimal glands help prevent the eyelids from sticking together when the eye closes. These tears create a thin layer of moisture on the surface of the eye and eyelid, allowing for smooth and comfortable blinking.
Your eyelid helps you to keep out the dust and dirt out of your eye. Your welcome!!
