Hi Wayne.I can relate to the increased short wavelength / UV sensitivity with a clear lens. My eye surgeon was very interested in my feedback around how the new lens affected my color perception, given my job.About a month after my surgery I emailed my surgeon color graded photo of an image in a GTI viewing booth, but in two views. The color as it appeared to each eye.I have attached a link to it below. I did wonder at the time of selecting a lens, if the eye surgery folk that engineer the spectral transmission of those lenses had heard of the two degree standard observer. Could be a great collaboration there for some folk on this list maybe? :-) Peterhttps://drive.google.com/file/d/1Xoqdyc2LuKywA7rkodHEn-zJ71heIvw9/view?usp=d...

I got UV absorbing lenses in both eyes, and during the time I had only one replacement, the difference was quite noticeable. A colleague who had one UV absorbing and one clear reported some extreme differences. I had a khaki colored parka that was mainly cotton, but synthetic knit for the collar. In daylight, I saw a slight mismatch, but he saw a strong purple cast to the collar. I wear photo gray glasses, and I can see an amber tint under artificial light and a much stronger amber tint under daylight. My natural lenses had browned to the point that I could not see the tint.
