Google X, the secretive research lab famed for its work on Glass and Google's self-driving cars, has unveiled its next product: Smart contact lenses. The first smart contact lens, aimed at diabetics, takes a glucose level reading every second from the tears that wash over your eye when you blink, and transmits that data wirelessly to a nearby device. Google doesn't say what device, but presumably a smartphone or Google Glass. Yes, if Google X has its way, we will soon all look like cyborgs, our bodies becoming networks of implants and augmentations.
