The tradition of the nazar is over 3,000 years old. People in Turkey, Greece and many other countries have used these blue eyes as little 'good luck pebbles' for a long, long time. The idea is friendly: the bright blue eye looks back at the world and keeps things going well.
Each nazar is made of melted glass. Workers in small workshops drop hot, glowing blobs of glass onto metal rods, then layer different colours on top - dark blue, light blue, white, then a black dot. When the glass cools, the layers set into a perfect eye shape.
You will see nazars everywhere in Turkey. They are hung above doorways, sewn onto baby blankets, fastened to bracelets and necklaces, and even attached to the keys of new cars. Tiny ones are given as little going-away presents.
It is one of those traditions that connects everyday life with something much older. A child today getting a small blue charm from their grandma is doing something a child their age was probably doing 3,000 years ago.
