So here's the thing, the laser goggle for UV light looked orange-yellow, which was sort of understandable, cause, if one want to block UV light, then the transmitted light ought to stay away from the UV spectra.
However, I suddenly realized that most of the the laser goggle I've seen for infer red light also looked orange-red. This became somewhat confusing. I sort of suspect that it might because the material blocked infer red but not red. Still, why the laser goggle for infer red laser still looked orange-red? What's the reason and common material for this result?
