Scientific American's Charles Q. Choi predicts that virtual reality contact lenses -- tiny full-colour megapixel displays that are transparent and hands-free -- could be available as soon as 2014, although solely for troops.
[...] Innovega researchers funded by the Defense Advanced Research Projects Agency and the National Science Foundation are developing novel contact lenses that can help view tiny full-color megapixel displays.
[...] The new system consists of advanced contact lenses working in conjunction with lightweight eyewear. Normally, the human eye is limited in its ability to focus on objects placed very near it. The contact lenses contain optics that focus images displayed on the eyewear onto the light-sensing retina in the back of the eye, allowing the wearer to see them properly.
Conventional mobile device screens are often too small to read comfortably "and certainly too small to enjoy," Willey said. In contrast, Innovega's contact lenses could effectively generate displays with a screen size "equivalent to a 240-inch television, viewed at a distance of 10 feet.
