KM unless for some obscure reasons the relative wavelength distribution is more important than the absolute intensity
Yeah, that is what I had thought too, and that is why I am considering the glasses. I do have orange UVEX goggles worth USD 10. They do not help, although I verified with a spectrometer they effectively cut blue and green. The optician says the low quality of those lenses may cause more downsides than benefits, but I have not yet fallen to purchase his Nikon lenses which are over USD 400 inclusive of frame.
I am really desperate and wondering whether it is worth to eventually waste other bucks rather than sit here and do nothing. That for sure is not leading anywhere. To be honest the main reason why I have not yet made the investment though is that the guy showed me a bunch of lens colors from bluish, purple to yellow, but was unable to tell me why one rather than the other. That proves to me that, no offense, he is not competent. "Some people find a certain color more comfortable" is not a satisfying scientific / technical explanation. I won't be allowed to swap lens color if it does not work.
