A blind man can make out objects again after an optogenetics treatment | MIT Technology Review Skip to Content The 58-year-old man was blind, barely able to perceive whether it was day or night. After receiving gene therapy to add light-sensing molecules to one of his retinas, he could locate a notebook set on a table. Scientists in Europe and the US are reporting today what they describe as the first successful use of optogenetics to improve a person’s vision. The feat involved introducing a gene from algae into the man’s retina. “I think that a new field is being born,” Botond Roska, a profe
