Talismans or amulets created to protect against the evil eye are also frequently called "evil eyes".[5][failed verification] [6][failed verification] Older iterations of the symbol were often made of ceramic or clay, however, following the production of glass beads in the Mediterranean region in approximately 1500 BCE, evil eye beads were popularised with the Phoenicians, Greeks, Romans and Ottomans.[7] Blue was likely used as it was relatively easy to create, however, modern evil eyes can be a range of colors.
