bionic contact lense
I'll give it a few years to develop and then I'll buy them to play whatever the best FPS is at the time.The bionic eye has arrived: engineers have, for the first time, combined a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.
The lens could give wearers a new look at the world by superimposing computerized images onto their natural view.
Such virtual displays could be useful to drivers and pilots, who could obtain route, weather, or vehicle status information overlaid onto their vision. Video-game players could immerse themselves in a virtual world without restricting their range of motion.
The lens could even be paired with sensors that monitor a person's biological conditions -- cholesterol level or the presence of viruses and bacteria, and transmit the data wirelessly to a computer.
