New Technologies Focus on Sharper Artificial Sight

In 2014, a futuristic treatment brought some version of vision to the blind. A device called Argus II transmits signals from cameras mounted on glasses to a tiny grid of electrodes placed on the back of the participants’ eyes. It replaces signals from cells lost to retinitis pigmentosa, a genetic disorder. Manufactured by Second Sight, the glasses and implants have helped 350 people to date. Argus II presents crude forms of artificial images. Users can make out spots of light but require the assistance of canes and guide dogs to get around. Still, it was a beginning. In a world where prescription glasses can be ordered online, readers are available at the drugstore and Lasik can restore perfect vision to appropriate candidates, anything seems possible. As the research progresses, the blind may gain or regain their sight in more tangible ways.
