Sony's Contact Lenses Can Take Photos
A filing on the U.S. Patent Office's website (available here) reveals a "digital" contact lens device. Simply put, this patent reveals a device that acts as a contact lens, but can take photos and send them to another device such as your phone.
The details specify that it is capable of capturing an image simply by closing your eye for a certain time period. There is also elaborate description of how it would interface with a user's device, and how configuration of the lens could occur from the device, and the captured image would be transmitted back to the "host" device. You could also "tilt" the lens via a gyroscope sensor. It also appears to be able to "display" the image after capture.
