Jay Neitz and Maureen Neitz may have found the cure to red-green colorblindness with one simple injection. They inject a virus into the eye that can distinguish the correct part of the retina to treat using gene therapy. The Neitz's are currently conducting an experiment using it with red-green colorblind monkeys and has deemed very successful. However, introducing new colors to humans brings up the topic of how people respond to the new stimuli and the possibility of psychological issues. Thus far, there has not been any noticeable psychological stress on the monkeys, but they must make it as safe as possible before administering the gene therapy treatment to humans.
