Why can the nerve in my eyelid twitch and how do i stop it?

Irritation: It is not usually the nerve that twitches, it's the muscle. The eyelid is a sandwich made up of skin, muscle, cartilage and lubricating glands. When the glands become infected or irritated they annoy the adjacent muscles and a twitch, or myokymia, results. Warm compresses, lid hygiene and drop medication can often make it better in a hurry.
