back to article Now we're cookin' on gas: Google crafts sugar-alert contact lens for diabetics

Google's skunkworks "X" lab is building a contact lens that can monitor glucose levels in the tears of diabetics, and warn them when it drops too low. The wireless-communicating device was unveiled by Google in a blogpost on Thursday, and may also one day contain tiny LEDs that'll light up if the wearer becomes hypoglycemic …

    Somebody won't be happy

    CGM and fingerprick tests

    CGM and fingerprick tests are currently complementary. Finger prick tests give you an instant, accurate (+-20%) reading but has the limitation that you rarely have more than 10-12 data points per day. CGM is testing every 5 mins but the reading is roughly 20 minutes behind the blood test.

    So both are useful - the CGM gives you trending information which helps with determining how your BG is affected by food, exercise etc.
