An injection of nano particles into the eyes of mice temporarily gave them the ability to see near infrared light (NIR) as green; the effects lasted about two weeks. This is very similar to night vision goggles without any hardware. Both rods and cones are affected so in theory the injection would be viable for humans.

That's gotta be seriously fucking annoying when you don't need it. What would you see when you were looking at both red and green traffic lights, or generally out in the sun on a clear day?
Maybe not blindness, but definitely headache city.
