Google has invented a new smart contact lens with an integrated camera. The camera would be very small and sit near the edge of the contact lens so that it doesn’t obscure your vision. By virtue of being part of the contact lens, the camera would naturally follow your gaze, allowing for a huge range of awesome applications, from the basis of a bionic eye system for blind and visually impaired people, through to early warning systems (the camera spots a hazard before your brain does), facial recognition, and superhuman powers (telescopic and infrared/night vision).
