The idea of information being presented directly to your eyes, be it by glasses, contacts, distant lasers, or brain implants, has existed for decades. But like so many sci-fi concepts, the engineering is slightly more difficult than the idea work. While we’ve seen lots of work in artificial eyes, head-mounted displays, and cortical implants, the on-eye display has remained elusive. Progress is being made, though. Researchers at the University of Washington and Aalto University in Finland have successfully created a simple wireless contact lens display and tested it on a live eye — a proof of concept that may presage more sophisticated devices. People wonder what kind of display comes after the touchscreen; it may be something like this.
