Alain Herzog / 2021 EPFL Retinal implants can deliver artificial vision The camera embedded in the smart glasses captures images in the wearer's field of vision, sending data to a microcomputer placed in one of the eyeglasses' end-pieces. Being able to make blind people see again sounds like the stuff of miracles or even science fiction. And it has always been one of the biggest challenges for scientists. Diego Ghezzi, who holds the Medtronic Chair in Neuroengineering (LNE) at EPFL's School of Engineering, has made this issue a research focus. Since 2015, he and his team have been developing a retinal implant that works with camera-equipped smart glasses and a microcomputer.
