Google Contact Lens Cameras?

CNET says Google is working on it:

Google has a patent pending for a contact lens with a micro camera and sensors embedded on the surface controlled by blinking, which would enable you to take hands-free pictures and could help the blind navigate the everyday obstacles of the world. Although still apparently hypothetical, the patent combines ideas from Google Glass smart glasses and Google's tear-scanning smart contact lenses. Highlighted by Patent Bolt, the smart-contact-lens patent posits sensors in the lens that can look for light, colours, faces, movement and even specific objects.
