Ray Bans were almost universal a few years back,but I stopped wearing them after watching a documentary on the TV.
The parent company that own(ed?) ray ban were formost a cosmetic company and single handedly wiped out an entire species of monkeys to use for testing .The scenes were horrific, large groups of monkeys were trapped and only the ones of certain age were taken to be used,the others being clubbed to death or the old/injured ones just being left to die.
