Apple reportedly has a secret team working on developing sensors for non-invasively and continuously monitoring blood sugar levels to help treat diabetes.

This goal is considered a “holy grail” by many researchers, due to the challenge of tracking glucose levels accurately without having to break the skin to do so. Clearly Apple’s aiming as high as ever!

Finger prick testing could soon be a thing of the past for people with diabetes, thanks to new smart contact lenses being developed by Google that measure glucose levels in your tears. The lenses have tiny chips and LEDs embedded within them, which light up to notify the wearer that their glucose levels have crossed certain thresholds.
