Sunglasses are one of those things that are nearly impossible to find without a 2000% markup. I'm too lazy to do the research. Tell me your nerd secrets.

If you have a UV lamp and UV paint, you could use them to test. If you're the sort of person who has both those things
That might work! I think testers usually try to distinguish the UV-A and UV-B spectra but maybe the paint would be good enough.
I wonder if different paint colours respond differently. I only mentioned it because I have some for warhammer.
Sounds like a cool experiment!
