Google unveils smart contact lens for diabetics

The development of a ‘smart contact lens’ may help people with diabetes manage their blood sugar levels and serve as an alternative to taking blood samples, according to Google, which unveiled a prototype lens.

Members of the Google X project team began work on the smart lens about 18 months ago, with the goal of creating a device that diabetics could use to monitor their glucose levels at all times during the day. The lens works by using microscopic chips, sensors and an antenna to track glucose levels in human tears. The current prototype produces one reading per second.

Google is currently working on using miniature LED lights that could light up as a warning when glucose levels are abnormal. Several clinical research studies have also helped refine the prototype. However, Google said the product still has to undergo about five more years of research and review by the Food and Drug Administration (FDA) before it could be available to the public.
