Sony has patented a contact lens that comes with an integrated miniature camera module and all its components, such as image sensor, lens, processor, storage and even a wireless module to transfer images to a smartphone or other connected device. The camera is triggered by a "conscious" eyelid aperture and closure. A sensor measures the pressure of your eyelid, and other settings such as aperture and zoom can be controlled via eyelid movement as well. A display unit allows you to view captured images directly on the lens. The patent document says the following about the camera module:

"The image pickup unit includes, for example, a lens system including the image pickup lens, an aperture stop, a zoom lens, a focus lens, and the like, a drive system that causes the lens system to perform focusing operation and zooming operation."

There is even a digital image stabilization system to counteract image blur caused by motion of the eyeball. Google and Samsung have filed for similar patents before but with its range of controls the Sony variant is, at least on paper, the most advanced so far. It's impossible to know if a product like this will ever hit the market but if it does, it's certain to raise even more privacy concerns than Google Glass at the time.
