From this article at IEEE Spectrum:
“Augmented reality in a contact lens? Science fiction writers envisioned the technology decades ago, and startups have been working on developing an actual product for at least 10 years.
Today, Mojo Vision announced that it has done just that—put 14K pixels-per-inch microdisplays, wireless radios, image sensors, and motion sensors into contact lenses that fit comfortably in the eyes. The first generation of Mojo Lenses are being powered wirelessly, though future generations will have batteries on board. A small external pack, besides providing power, handles sensor data and sends information to the display. The company is calling the technology Invisible Computing, and company representatives say it will get people’s eyes off their phones and back onto the world around them.”
