Why does our eye twitch?
Little lid spasms are common, but they can sometimes be a sign of trouble.
A slight tremor of the eyelid—the type that shows up without warning but scrams just as suddenly—is usually no cause for concern, explains Dr. Wayne Cornblath, a professor of ophthalmology at the University of Michigan’s Kellogg Eye Center. “I think everybody has these once in a while,” Cornblath says. “You rub it, and it eventually stops.”
He’s talking about the kind of whispery muscle spasm that happens in one eyelid (or just a portion of the lid, to be precise). It can be a nuisance, but it usually goes away on its own within a few days, if not a few minutes.
