Kind of depends on their use and there are many to choose from. As far as properties; most are Polycarbonate and sideshields are a must. Harbor Frieght would be the low end and from their, the price goes up. In my previous lives, I had to wear persription safety glasses that I also used for sooting. Then you have some that are tinted. I own a pair of cases S&W shooting glassses that were "pretty". They mostly sit in the drawer. ......Can you recommend me some?
Theres some out there that have very wide stem (or ear piece, temple, whatever you want to call them) that also tend to flex away from your head. Those will render a good set of ear pro almost useless. Many shooters don't even realize why their ear pro doesn't work so well. The very smallest, thinest, tightest to the head glasses seal the best.
