Eye twitching

Eye twitching, or myokymia, is an involuntary eyelid muscle contraction that usually affects the lower eyelid. The exact cause of an eyelid twitch is unknown. A twitch sometimes develops during times of increased stress. Twitching has also been associated with high caffeine intake, fatigue or excessive squinting.
