A nazar (Turkish: nazar boncuğu Old Turkic: gökçe munçuk) is an eye-shaped amulet believed to protect against the evil eye ("evil eye", from nazar and "amulet" from boncuğu). The word "nazar" is derived from the Arabic, "sight" or "seeing". In Turkish, it is called Munçuk. In Central Asia, during the ages of Tengrism, people held similar superstitions like horseshoes, garlic, wolf's tooth, dried thorn, lead, stones; but the crystal blue eye has always been the most popular one.
It is a common sight in Turkey, Albania, Greece, Cyprus, Syria, Lebanon, Egypt, Armenia, Iran, Afghanistan, Iraq and Azerbaijan, where the nazar is often hung in homes, offices, cars, children's clothing, or incorporated in jewellery and ornaments
A typical nazar is made of handmade glass featuring concentric circles or teardrop shapes in dark blue, white, light blue and black, occasionally with a yellow/gold edge.
