Only cooperation with France and the west has made this possible. There has already been at least one damaging incident that needed a group think to solve.
However, I think those methods of triggering opsins are rather invasive (implants). I don't think it would be hard to design light activated opsins to recieve frequencies in the optical window of skin/bone. If I remember correctly the human body is somewhat resistant genetic transfection, so we have that going for us, which is great.
There is an optical window for skin in the near infrared band.
