Everr noticed that all the windows and doors are painted blue? There's a reason for that! Blue protect you and your home from 'evil spirits' to enter the home. Another superstition ... I'm sure that you saw many little eyes for sale, some are cheap but some are made of gold and precious blue stone as an eye ... many many Greeks wear that, why? It protects you from someone giving you the 'evil eye' and throwing a bad karma your way! Greeks are very superstitious that way.
