Deuteranomaly and protanomaly -- the most common conditions referred to as "red-green colorblindness", and which involve variant forms of light-sensitive pigmen

Deuteranomaly and protanomaly -- the most common conditions referred to as "red-green colorblindness", and which involve variant forms of light-sensitive pigment in one set of cones -- do not involve inability to distinguish red from green. Deuteranomaly causes difficulty distinguishing between shades where the precise amount of green is relevant (i.e., to a deuteranomalous person, pure yellow -- equal parts red and green -- would still look slightly reddish-orangish). Protanomaly causes a similar effect with red, and also dims the dark/deep red part of the spectrum slightly. If someone doesn't want to use the medical terms for them, better names are "green weakness" and "red weakness" since they don't carry the misleading "can't tell red and green apart" connotation.

I apologize for my ignorance of the specifics of color blindness, I don't suffer from it myself. I've just been so fascinated by the concept of these glasses that I can't help sharing.

  There is also a very large range of responses to the EnChroma glasses. I've seen or heard about plenty of intense reactions to them, but my personal experience has not reflected that. My brother-in-law and I are both colorblind (mine is not as severe as his) and he bought a pair a few years ago. He enjoys the difference but not enough to wear them consistently, and they had a barely perceptible effect on my own vision, just giving green a bit more "pop". I think the main issue is that it's easy to group all colorblindness together even though "huh, I guess my shirt really is purple" is very different from "I look at streetlight positions, not colors." That said, even my mild colorblindness puts me at a massive disadvantage on certain Halo maps or against certain team colors. In situations like that, I might as well be fully colorblind asI end up having to play based on movement alone.

    I always assumed the large range of responses was due to a large variation in the way color blindness manifests. Also perhaps on how your neurons have adapted to the condition; I wonder if age plays a role?
