It is not just stress and caffeine, but any sort of irritation that causes the muscles in the eyelid to spasm. Most often it will stop on its own. If it goes on for more than a couple of weeks, see your eye doctor. A botox injection can help. Another word for this is blepharospasm if you want to do a search for that. I have had twitching in my left eye for over a month due to dry eyes and irritation from having my tear ducts plugged. I just live with it!
