I was curious about this too and did a test firing a pneumatic pellet gun, set at 500 fps, directly into the lenses of both the Uvex shield and poly-carbonate glasses from 5 feet away. Both items were propped-up with items behind them so they would absorb all the impact and not get knocked away. In both cases, it only made a slight dent in the plastic. It performed much better than I thought. Of course, a larger or perhaps sharper piece of metal might penetrate. I suspect a grinding wheel blow-out would be bad news for those lenses but at the very least, it will no-doubt slow down flying particles -helping to put the odds in your favor.

i have a pair of cheap, clear plastic safety glasses that are very lightweight, and i often forget their on.i also have a pair of the ones withlights on the sides, but havent used them yet. i insist my 10 yr old son wear safety glasses when doing about anything with me shop-wise. i even make him wear them to run the weedeater. i most often wear sunglasses to ride my bicycles. God only gave me two eyes for a whole lifetime.
this brings up a question, my cheap, comfy clear glasses,either from hf or wallymart,not sure now, how safe are they really? i dont have the package anymore, and didnt think to read it when i opened them. maybe i should get stronger ones? i geuss im trying to say id like to add some talk about ratings, or facts about which ones are better protectors to this very important discussion.
thank you, and im glad to see that so many of us DO protect our lookers
