The evil eye is a curse believed to be cast by a jealous glare, usually given to a person when they are unaware. Many cultures believe that receiving an evil eye will cause misfortune. When a person wears or carries an evil eye with them, it guards them against misfortune happening. The evil eye will bring good luck and protects any ill-will that could otherwise have a negative effect on you. If it falls off or breaks it protected you from an evil eye.
