If I take a cheap pair of safety glasses and move them around in front of my eyes, I can tell they warp my view. Is this inherent in all safety glasses, and how does it impact point of aim?
I've given up on cheap glasses for the same reason and only use the more expensive stuff now: Oakley, Wiley, Scott, etc. Among these, I'm not picky. They're all better than the glasses sold at gun/bigbox stores.
