All of the trial participants were made blind by retinitis pigmentosa in which the light-sensitive rods and cones of the retina deteriorate. British participants Robin Millar and Chris James, whose retinas had not responded to light in over a decade, were able to see immediately after the chip was turned on. Seeing the first flashes of light, James told the BBC, was a “magic moment.”"
