Smart Contact Lenses

"Google and Novartis hope to launch smart contact lens in five years":

The two companies have a few ideas for a smart contact lens. The first is the original glucose-monitoring lens, which could detect a diabetic person's glucose level via his or her tears. The second is an "autofocus" lens for people who have difficulty switching between near and long-distance vision. Novartis said this focusing problem affects 1.7 billion people, with Joe Jimenez, Novartis' chief executive, calling it “the holy grail for vision care.”
