Review (2/5): About 1/2 the thickness of "standard" ones but the worst thing is the smell
These are very thin & flimsy compared to what was on my glasses previously... That would be OK & they would be serviceable if not for the strong smell they give off. And have given off for the 2 days they've been on. It's a strong chemical smell & is of course right near your nose:)
I won't be using these, will spend 2X their price or so & get usable ones.
