Researchers at the University of Washington report in the journal Nature that they have been able to restore full color vision to adult monkeys born without the ability to distinguish between the colors red and green.
According to National Public Radio, scientists who study color vision are calling the study dazzling.
Until now scientists thought that this sort of therapy was not possible. However, the University of Washington team were able to introduce therapeutic genes into the light-sensing cells at the back of the eye of adult male squirrel monkeys, who are born red-green colorblind.
Furthermore, the monkeys were treated over two years ago and their improvement in color vision has remained stable since.
