I started getting an eyelid twitch just within the past couple of months, and my doctor says it it most likely just stress. Most of those tics people get - an eyelid, the cheek, or whatever are just stress related. Close your eyes and take a couple of deep breaths and I bet it will calm down! (Of course if it's actually your EYE and not your eyelid twitching, I would suggest going to the optometrist.)
