>>973168>Cotton isn't water resistantIt depends on the cotton, and whether it's treated, and your definition of "water resistant," kind of like how it depends on the plastic, and whether it's treated, and whether it meets your definition of acceptable. First world manufacturers of eye protection have a definition. That definition is not yours, apparently, since you think "will attenuate" is the working industry definition of UV protection.
And why do you keep going off on polycarbonate in particular? As if you are claiming it's an inherent property to dodgy fake fashion eyewear from ali express that it's made of the precise kind of optical material that fits your agenda, or that "attenuate" is the same thing as "block 100%". Many kinds of materials are used to make lenses. Most of them "will attenuate" UV. But that's an intentionally misleading definition of UV protection. Did you get those glasses tested in a lab? Are you a polymers expert? How do you know that it's polycarbonate? How do you know how much UV passes through? UVA? What about UVB? Oh, "some of it got blocked", well I guess it's just as good as eyewear where the manufacturer actually followed first world quality control protocols.
You seem to actually think some low-paid guy whose job it is to duplicate the oakley logo perfectly is going to worry about passing ANSI spec
Go bang your head against the wall until you've calmed down, then learn to use a search engine, then never post on this board, or anywhere on the internet, ever again
