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.
