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.
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.
