I have found that McMaster-Carr's 55035T3 are the best all around safety glasses. They are fog-free (really), easily go over prescription glasses, are comfortable with adjustable angle and ear pieces, and the frame can be reused on new lenses which can also be purchased (55035T92). I keep these for people who don't need safety glasses enough to justify safety prescription lenses.

Personally, I have a set of prescription safety glasses. They have a set of prescription lenses in a frame under a Uvex safety shield which can be replaced. Still the same number of surfaces to look through, but only one thing hanging on your head. The replacement shields are available on-line for a few dollars, but you still have to buy new prescription lenses whenever you get new (regular) glasses. The expense is justified by keeping the only two eyeballs I will ever have safe. There are just some things you don't skimp on!
