True, but couldn’t they make a visor that could do that for normally functioning eyes? Like, he could wear it as needed and see the world like normal too?
You would have to lose some sort of color if you use regular retinas to see a larger spectrum. You’d need new retinas with more cones to get new colors. Fun part is, you could have those colors all be translated into visual light if you do have more cones. More cones let you differentiate color better and thus gives you more discernable colors. Tetrachomats can interpret a broader spectrum that way.
They address this at some point. Something about him not having eye nerves made direct access to his brain via the same neural pathways possible+ necessary. I believe the visor turns the entire EM spectrum directly into neural signals that his brain interprets as sight.
