Well, it seems like this is not for the color blind per se (which would be people with dichromacy or monochromacy, who lack certain retinal cones altogether) but those with anomalous trichromacy.
However, anomalous trichromacy is the most common form of color vision deficiency, so yeah, great for them. This is actually pretty clever, even though in essence it's actually only some very selective dark glasses.
