I've had a number of eye twitches from time to time. I had one for a couple months at the end of last year. My left eye would twitch every time I sneezed or yawned, and it also seemed to twitch sometimes when water hit my face in the shower. It happened several times every day. It was so annoying (and, of course, it worried me). At some point, it just stopped. No explanation! I've always been told these are harmless and often brought on by stress and/or lack of sleep.
