Google to make smart contact lenses

Google to make smart contact lenses: 

Google is developing smart contact lenses that measure the glucose levels in diabetics' tears. The prototype contacts are outfitted with tiny wireless chips and glucose sensors, sandwiched between two lenses. They are able to measure blood sugar levels once per second, and Google is working on putting LED lights inside the lenses that would flash when those levels are too low or high.

The electronics in the lens are so small that they appear to be specks of glitter, Google said. The wireless antenna is thinner than a human hair.
