The evil eye is a legend or a curse which is believed to be cast through a spiteful stare (usually due to envy). Some cultures believe that this malevolent glare may cause injury or misfortune and is usually given to an individual who is unaware. Also, the created talismans which are meant as protections from the evil eye are also termed as “evil eyes”. These charms are often circular with a dot or an iris in the middle. They are also the ubiquitous cobalt-blue eye decorations in souvenir shops in Istanbul and ocular ornaments worn by some people. This belief is held by several social groups in various parts of the globe including Portugal, Turkey, Greece, Iran, Morocco, and Italy. Superstitiously, some groups believe the markings of a peacock's tail is a display of the evil eye.
