Google Testing Smart Contact Lenses That Measure Glucose Levels In Users’ Tears.

Google has been awarded “a patent for a contact lens with an embedded chip” that may help measure glucose levels in people with diabetes. The company “has been testing various prototypes of smart contact lens and is currently in talks with the US Food and Drug Administration (FDA) about a lens that measures glucose levels in users’ tears.” Google “says the chip and sensor are embedded between two layers of contact lens material and a tiny pinhole lets tear fluid from the eye reach the glucose sensor, and the sensor can measure levels every second.” http://time.com/3758763/google-smart-contact-lens/
