The evil eye is when someone looks at you in a way that some people think is bad. Some people believe that when someone looks at you in this bad way, it can cause bad luck or harm to come to you. People believe this all around the world and it has been around for a really long time. Some people try to protect themselves from the evil eye by wearing special jewelry or putting up things like beads or pictures to protect them from being looked at in the bad way. But, it's important to remember that the evil eye is just a belief and not everyone believes it's real.
