Smart Contact Lenses can record what you see

•The race to develop smart contact lenses with all kinds of crazy capabilities is getting more focused.

Sony became serious contender by filling a patent for self-powered contacts that could record by built-in camera,play and even store videos right before your eyes.

•With Google and  Samsung having already filed patents for contact lenses with tiny,built-in cameras and they have the potential to change everything about the way we interact with each other, for better or worse.

•That means in the future we could all be playing back recordings of old conversations to our friends and family. Potential misuses aside,the technology behind these new 'Smart Eyes' is actually incredible.

•The device would be controlled by consciously blinking in a certain way,prompting it to start or stop recording. Since the wearer blinks normally,effectively covering the lens for 0.2 to 0.4 sec each time.The lens could automatically delete dark frames for better playback,Sony's patent explained.

•An antenna in the lens allow for transmitting the captured image wirelessly. Those who need Prescription lenses would wear a corrective lens in one eye and the recording lens in other eye.
