DIY Invisible Implant Helps The Visually-Impaired Navigate
Rich Lee implanted a magnet in his ear that can be used as an echolocation tool for the blind.
Rich Lee is a grinder. Grinders perform do-it-yourself body modifications and enhancements to improve the human bodily condition, and are part of the larger biohacking movement which brings a hacking mentality to biology. Lee is partially blind with a diagnosis of eventual total blindness, so he hacked his body and installed a magnet into his ear to act as a speaker.
