What is the evil eye ?
The evil eye is a belief that a person can harm you,your children, or your belongings simply by looking at them with envy and praising them. Jealousy, envy, or praise can inflict all kinds of misfortune on the object of desire whether if it is a person or simply an object of desire. The penetrating look is believed to cause illness, damage, injury, or death upon its intentional or unintentional target. Most common is the belief that the evil eye can cause things to whither away or dry up -- the loss of crops, drying up of milk in nursing mothers, impotency in men, illness among children, are all commonly attributed to the evil eye.

The evil eye wards off this danger by protecting the individual or their belongings from the jinx or misfortune that can be caused by the evil eye.
