Color vision established through genetic engineering

National Public Radio reports that scientists have enabled two monkeys, from a species that does not see in full color, to perceive colors they could not perceive at birth. The "cure" was not immediate, presumably because it took a few months for appropriate neural connections to be established.

If the same techniques worked in humans, perhaps, as the authors say, a variety of eye problems, and perhaps other problems, could be treated in this way.
