Sony has patented a contact lens that is blink powered and records video

Unlike other forms of contacts and glasses that created an augmented reality or hook you up to the internet, Sony's new patent is on a simple set of contacts that can record video.

The recording is turned on and off with the user's blink and sensors can detect if it was an intentional or unintentional one.  The image capture technology and data storage would be held within the lens.

Simple, piezoelectric sensors would allow the movements of the eye to charge the battery of the device.

The task, now, is to fit all of this technology, comfortably, into the lens.
