No one knows for sure what causes twitching of the eyelid. Some doctors believe that rest and stress reduction may help. Sometimes pressing on the twitchy area for a few seconds provides temporary relief. If it hasn't gone away after three or four weeks, though, consult and eye-care specialist. If a thorough examination uncovers no underlying cause and the twitching is particularly severe and persistent, you may want to ask about the possibility of injecting botulinum toxin (Botox) to certain muscles around the eyes to stop the twitching. There are risks, however, since Botox is a drug that temporarily paralyzes muscles. And some doctors think that would be overkill for patients with chronic, unremitting eyelid spasms. And good luck.

They are involuntary spasms of the eyelid often caused by fatigue, stress and caffeine. They will eventually go away.
