Safety glasses are required for my job at all times on the factory floor. I have had good experience with Patriot brand over-the-glasses style safety glasses; I can wear them for 12+ hour shifts without discomfort. They do scratch, but if you take close care of them that isn't an issue. I usually don't realize that I'm wearing them at all.

I've used side-shields with my normal glasses, but only on occasions where safety glasses were obligatory but I didn't feel were necessary. Whenever there is the potential for flying bits of metal in the air, I will always put on a beefy pair of safety glasses that fully protect my eyes.
