Put A Camera On Your Eyeball

• Google filed a patent for a camera-containing contact lens.

• Sensors on the contact lens would detect blinks and respond to commands based on those blinks. 

• The camera sits below the pupil on the contact, so it shouldn't obstruct vision. 

• Because the camera is on the eyeball, it follows the wearer's gaze, potentially recording anything he or she sees, as he or she sees it. 

• Right now, the patent is to secure future innovation and is not yet linked to a marketable product.
