When your right eye twitches it means something good is going to happen. I have heard, when the top of your eye (say the eyelid) is twitching, something good is going to happen to you, but when the bottom of your eye is twitching, something bad is going to happen. If it is twitching really bad, the effectiveness is stronger than a little twitch.
A twitch of a right is associated with good luck superstition. It could mean that good events will happen to you like receiving good news, get money or achieve your expectation. Unfortunately, left eye twitching superstition indicate bad omen. Some people believe that having a twitch of a left eye is a sign of good luck as well.
