How the combination of retinal implant electrodes and smart glasses partially restores vision
Phoebe Harkin | | Quick Read
Researchers at EPFL’s School of Engineering have developed an implant that uses electrodes to stimulate retinal cells, offering a form of artificial vision. Smart glasses capture images in the person’s field of vision and send the data to a microcomputer that converts it into light signals, which are transmitted to the retinal implant’s 10,500 electrodes. The electrodes stimulate the retina so that the wearer sees a black-and-white version of the image made up of dots of light. To make out the shapes, the user must learn to interpret the dots of light the way one would constellations in the night sky. Though the technology is currently not authorized for clinical trials, the engineers are hopeful approval will come soon.
