People believe that thay must protect themselves from thr evil eye of another person by putting turquoise beads in various places. A blue bead is pinned on newly born babies because babies are more vulnerable to an evil spirit and must be protected. Since houses must be protected, too, a blue bead, usually with a horseshoe, is placed near the doorway for protection against someone with an evil eye. Also, if people have an item of special value like a car or sewing machine, they must protect it with a blue bead.
In conclusion, certain superstitions have become rituals with the purpose of protecting and bringing good luck. Because people always want to be protected and have good luck, these age-old superstitions are as strong today as they were ages ago and probably will continue in the future.
