It was not until the 1990s that this invention became better known throughout the world. Covert, fashionable, and normal—looking embodiments led to its acceptance. The apparatus, which causes the eye itself to, in effect, function as both a video display system, and a camera, is concealed inside what look like ordinary sunglasses. Several very powerful computers, including some with video processing hardware, a graphics rendering engine, a web server, and mass storage, are concealed under ordinary looking clothing. After more than 20 years, the invention has finally come of age.
