Photos of the Day: Restoring Sight
A tiny video camera mounted on special glasses captures the scene in the patient’s environment, and a pocket controller relays the captured video signal to the implant.
Inspired by cochlear implants that can restore hearing to some deaf people, the retinal implant works by electrically stimulating nerve cells that normally carry visual input from the retina to the brain, and bypassing the lost retinal cells.
“Jones’ work was one the most important technological developments needed to make the device possible,” said Douglas Shire, engineering manager for the Boston Retinal Implant Project.
A research assistant holds the implant, which was designed for people who lost vision due to injury to the eyes.
