Look into my eyes

They're hard at work on futuristic-sounding technology that uses smart contact lenses and implantable lenses to diagnose, monitor, and treat a wide range of diseases. In 2014, two of the largest multinational companies made an announcement that brought this new technology into sharp focus. Google, through its biology offshoot, now named Verily Life Sciences, and the Swiss pharmaceutical giant Novartis International, through its eye care division Alcon, joined forces to design, develop, and commercialize smart contact lenses for diabetics. If the project reaches its goals, these lenses will spare diabetics from the daily finger pricks typically used to measure blood glucose levels, instead employing embedded microelectronics to measure glucose in the wearer's tears.
