Despite being millimeters from your retinas, the images created by the lenses will be in perfect focus, and when the display is turned off, everything will be transparent. Since the lenses are inside your eyelids, though, you can’t un-see anything that they decide to project, which is something that you’ll have to consider when you’re watching something especially scary or gross on them. Power will come from a beltpack that transmits electricity wirelessly to a resonating antenna in the lens itself, and data will be transmitted the same way so that you don’t have to plug HDMI cables into your eye sockets.
