The evil eye, known as “mati” in Greek culture, is a curse thought to be given by a malicious glare that can cause bad luck or loss. You may have heard someone giving you the "evil eye" and knowingly wish negative thoughts on you.
That's why it's important to wear an evil eye somewhere on your body to ward off this curse and protect yourself throughout the day.
Every color is associated with a different meaning. Black represents power & aqua represents health.
