Oddly enough, I watched a show the other day (Shadow Hunter-Canadian show) and it was based on 'The Eye'
Many cultures revere the 'eye' symbol, and use it to ward off danger and curses rather than incite them.
I am thinking it was India (could be way off as I wasn't really paying too much attention) that the show focused on and there beliefs.
A large amount of ornamental jewelry is made to resemble the eye in some aspect, and used in these beliefs.
