People with CVD pretty much spend their lives compensating, sometimes without even knowing it. It usually takes some kind of glaring mistake to unveil that a person doesn’t see in a full color spectrum – like if an elementary school kid draws a purple tree instead of a green one. It seems almost fitting then, that the science behind EnChroma glasses – glasses that enable people with a color vision deficiency to see the world in full color – was also discovered by mistake.
