Saint Michael the Archangel, defend us in battle. Be our protection against the wickedness and snares of the devil. May God rebuke him, we humbly pray; and do Thou, O Prince of the Heavenly Host - by the Divine Power of God - cast into hell, satan and all the evil spirits, who roam throughout the world seeking the ruin of souls. Amen.

Evil Eye. Started with Turkish culture, now popular worldwide in many various cultures. It's NOT a religious thing, then it would be a sin if it was associated with it. But it's not, for Turks its cultural symbol! For others, it's fun nothing wrong with that!
