3D Printed Contacts Lenses with LED Displays--The Future Is Now

"Researchers at the University of Washington have created a contact lens with an LED display built into it. Whilst at present the contact lens device has only a single pixel of information, the researchers say it could be developed to display more complex information such as emails, creating a Google Glass-like contact lens, just one third of a millimeter in diameter," reports Newsweek. "Whilst theoretically it’s not difficult to build a display in a contact lens, actually fabricating the tiny, interrelated parts and then placing them on a miniature polymer disk is a very difficult task. However, the 3D printer, or 3D quantum dot LED printer to be more precise, has made this task a lot easier for researchers. Rather than the standard ‘domed plastic light bulbs’ that we recognize LEDs to be, the 3D printer works by sandwiching together different layers of interacting material, each with a different task."
