The evil eye

In much of southern Europe and Asia Minor there is the 'evil eye'
superstition, which I beleive is like a malicious curse. Believers in
the evil eye think that children and babies are particularly
suceptible to it. Would anyone like to speculate whether this
superstition originated from Indo-European mythology. Surprisingly
the tradition appears to be very strong in Turkey where 'good eye'
medalions are very popular to ward off the evil eye. I supose his may
be a legacy of the peoples who lived in Asia Minor before the Turks
invaded. Also how widespread is this tradition in other parts of
Europe?
