Eyelid twitching is a very common symptom. It often occurs in association with stress and fatigue. The exact cause is unknown.
Other than reducing stress and getting a little more good-quality sleep, there isn't any specific treatment for a twitching eyelid. It should go away on its own.
Some people find that a clean, warm, wet washcloth over the eye helps. While no proof exists that caffeine can make it worse, you might want to decrease caffeine consumption to see if it helps.
Eyelid twitching is not the same as a spasm of the muscles around the eye. Involuntary closing of one or both eyes, called blepharospasm, should prompt a call to your doctor's office.
