Display in midair

Despite the display being on the cornea of the eye, the image it shows would appear to be on an exterior object such as the windshield of a car, or might even seem to be in midair for people browsing the Internet or immersing themselves in a virtual world.

"Looking through a completed lens, you would see what the display is generating superimposed on the world outside," Parviz said in a statement when the research was made public last week. The images wouldn't obstruct a wearer's view, researchers added. "There is a large area outside of the transparent part of the eye that we can use for placing instrumentation," Parviz said.
