Chandrashekhar Chawan, an optometrist, wanted to offer his customers an extra sparkle for their eyes. Initially, he tried gold, but it didn't work that well. After his wife had diamonds mounted into her teeth, Chawan then realized that jewels present the luminous effect for which he was searching. Now he sells thick contact lenses with diamonds inside for $15,000 a set. Link -via The Presurfer | Photo: Shekhar Eye Research
