Simulate colorblindness in non-colorblind individuals Is there any way by which individuals with normal color vision could "see" the effects of Deuteranopia or any of the common colorblindness types, say by using special lenses or anything? 

Color vision deficits can be approximated via filters on images or video, but is there any way, via special lenses/eyeware or lighting that normal color vision participants could be made to actually perceive a scene as if they had a color vision deficiency from a normal colored object or representation?
One possibility would be to apply those image filters to a live video stream.

Aside from that, you could consider infrared goggles. Not an exact simulation of colorblindness, but it does apparently make red and green into the same color. And if anything, it would let people see the world in differently.
