Depicting the open right hand, an image recognized and used as a sign of protection in many times throughout history, the hamsa is believed by some to provide defense against the evil eye.
Talismans or amulets created to protect against the evil eye are also frequently called "evil eyes". Charms and decorations with eye-like symbols known as nazars, which are used to repel the evil eye, are a common sighting in many enlightened cultures.
The evil eye is a curse or legend believed to be cast by a malevolent glare, usually given to a person when they are unaware. Many cultures believe that receiving the evil eye will cause misfortune or injury, while others believe it to be a kind of supernatural force that casts or reflects a malevolent gaze back-upon those who wish harm upon others (especially innocents).
