I Am Sure Most Of Us Will Have Heard About Google Glasses,

but would not feel comfortable wearing them,

so Google has been busy working on another idea, inserting a smartcamera into contact lenses, the lenses were developed in the Google X lab and were featured in a patent filing dating from 2012, which was recently published by the US Patent and Trademark Office, the patent filing features a contact lens that includes an embedded circuit, camera and sensor, the control circuit could be linked wirelessly or via a wire to the camera and sensor, the sensor could be a light sensor, pressure sensor, temperature sensor or electrical field sensor, which may allow for people to gain a ‘sixth sense’ of sorts.”

one of the key benefits of having a camera embedded in a contact lens rather than attached to the side of the head like Google Glass is that the camera frame would follow a person's precise gaze without obstructing their view (by being placed along the edge of the lens, away from the pupil), Google points out that the lens could take raw image from a contact lens, process it and relay what it sees to a blind wearer via a different sense -- perhaps an audio warning that there is a car approaching a junction, for example, there may also be the option of go-go-gadget eyes that have a zoom capability, whatever will Google think of next?
