Google has recently announced a diabetes management project: Smart Contact Lenses. The lenses are able to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material. The data is then sent to a corresponding app, making it available to both the user and their doctor. The lenses are the latest in noninvasive continuous glucose monitors (CGMs) that are changing the way in which health professionals are addressing diabetes. At the moment, Google is testing prototypes that can generate a reading once per second, with less hassle and pain than current CGMs which are bulky and require needle sticks about once a week. Google scientists are also examining the potential for tiny LED lights that would serve as early warning systems for the user if the glucose level is out of range. Still in its clinical phase, Google Smart Contact Lenses can provide diabetes with a simpler management alternative.
