Yeah evidently the lenses filter those wavelengths out for our own protection, and supposedly some of it is perceptible to a degree for people who had the lenses removed. I remember reading somewhere that supposedly navies would use them as spotters, but I don't know how true that is, and it's a little difficult to search. People should also look up tetrachromia. Tetrachromats are people who [seem to] have an extra fourth type of cone that supposedly enriches the distinction between certain hues
