When your eye twitches, does that really mean it’s because you can expect to get a lot of money or run into an old friend? Actually, no. Blepharospasm, the scientific term for eye twitching, is a repeated, involuntary spasm of the eyelid muscle.
Doctors still haven’t found the exact reason behind eye twitches, but some potential causes are fatigue, stress, high caffeine consumption, dry eyes, and irritation to the eye.
