Photographer and retinal neuroscientist Bryan Jones puts his passions to work to explain (and show us) what color blindness actually looks like.
Also, for the record:
Lots of folks think that dogs and cats see the world in black and white. They, being dichromats, actually see the world in color very much like what a “color blind” person can see. They do not see only black, white and variations of that in grey, but do not have the same resolution as we do.
