Trivia
A nazar is an eye-shaped charm commonly found in the Middle East meant to ward away the Evil Eye.

The name might have come from the Indian saying "नसर न लगे" (Transliterated: "Nasara na lagē") which is said to keep that person safe from harms way. It may have also come from the Farsi word "nazar," meaning do not put.
