Gene Therapy Cures Color Blindness

Nature reports that researchers used gene therapy to cure a form of color-blindness in adult squirrel monkeys.

Lacking a visual pigment called L-opsin, these monkeys cannot distinguish reds and green. Scientists introduced the pigment gene into the eyes of color-blind adults. 1 month later, the monkeys with the new L-opsin gene could see hues they’d never seen before.

Research is not mature enough to be tested on humans, but it is promising
