Google has revealed their latest breakthrough in medical treatment: contacted lenses embedded with sensors to track the glucose levels of diabetics. According to the co-founders Brian Otis and Babak Parviz, Google X has already developed prototypes, done multiple clinical trials, and has met with the FDA for approval. This breakthrough may offer an alternative to the one out of every 19 people in the world who continuously need to prick themselves to check their glucose levels. "We're exploring integrating tiny LED lights that could light up to indicate that glucose levels have crossed above or below certain thresholds," Otis and Parviz wrote. "We hope this could someday lead to a new way for people with diabetes to manage their disease."
