Augmented Reality in a Contact Lens

A new generation of contact lenses built with very small circuits and LEDs promises bionic eyesight. Using custom-built optoelectronic components--integrated control circuits, communication circuits, and miniature wireless antennas into the lens. Those components will eventually include hundreds of LEDs, which will form images in front of the eye, such as words, charts, and photographs. Much of the hardware is semitransparent so that wearers can navigate their surroundings without crashing into them.
