Many cultures all over the world share a common belief in a type of curse or hex that is transmitted (usually) unwittingly through a glare or glance in which the caster is filled with envy, praise, or covetousness. It can also be transmitted, intentionally or unintentionally, by people with green or blue eyes — which is why protective charms to ward against this curse are so often blue, green, or turquoise.
The evil eye is also called the invidious eye, the envious eye, ayin ha’ra (Hebrew), malocchio (Italian), mal ojo (Spanish), jettatore (Sicilian), the stink eye (Hawaiian), nazar (Turkish), and bla band (Farsi).
While the eye itself is a receptive sensory organ, the power of the evil eye is insidious in its ability to send curses outward in a projective manner often unbeknownst to the own doing the cursing. In a traditional context, the person who sends the curse does not necessarily intend the afflicted target any harm. They simply admire and covet what they don’t already have. For this reason, mothers in cultures where a belief in the evil eye is prevalent might respond, “Oh, but he’s got dirt on him,” when told their baby is beautiful. Without saying something seemingly “mean,” the child might attract the evil eye and become sick — or even die!
Perils related to the evil eye include wasting, illness, blight, injury, plain bad luck, and possibly death.
Charms against the evil eye are sometimes also simply called “the evil eye” and take the shape of a blue, green, or turquoise circle banded in white to represent the eye. Various hand gestures and horns (with their phallic connotations) are also reputed to ward against the evil eye. Eyes, hands, and horns have all been fashioned into jewelry, charms, and art that can be displayed on bodies, in homes, and in vehicles to offer the most possible protection against the threat of this malevolent glare.
