Why does an eye twitch sometimes?

Question

what would be a reason for it

Answer 1

It is a superstition that if your eye twitches it means you are going to be happy or mad about something in the near future.

Answer 2

Probably because you're overtired. Just like other muscles twitch after over-use, so can your eye lid.

Eye twitching is usually stress related or due to a lack of sleep. Really.
