An Evil Eye bracelet is a piece of jewelry that symbolically protects its wearer from the perceived negative effects of someone who has given them the "Evil Eye." The Evil Eye is a glaring look that is intended to cause harm to the person it is directed toward. In this case, both the harmful look and the protective device are called the "Evil Eye."
The belief that certain individuals cause you harm or cause evil mischief to occur with just a look is one that historians trace across numerous cultures and from as far back as antiquity. Some cultures took the threat of the Evil Eye very seriously. For example, in Islam it is believed unlucky to accept a compliment without also stating "Masha'Allah," or "God has willed it," in order to ward off the power of the Evil Eye.
For some cultures, protective talismans in the form of Evil Eye bracelets became the most popular form of protection against the intended harm. In Mexico and Central America, bracelets featuring an eye are often placed on babies to ward off the Evil Eye, which could lead to their deaths. Another country that uses the Evil Eye bracelet to ward off evil is India, where the bracelets are crafted to be both beautiful and powerfully protective.
