According to one supplier, all safety glasses provide 99.9% protection against UVA and UVB (only welding goggles protect against UVC).
AFAIK, all safety glasses are made of polycarbonate, which automatically protects against UV. I have no problem recommending against drugstore "fashion" sunglasses though, which definitely aren't impact resistant and may not be UV protected either.
ETA: ooooh, a little higher priced than where I get them, but this site has the Mini Magnums in blue-blocking copper, indoor/outdoor gradient, and "Iridium"-style metallic reflective lenses. I'm stocked up at the moment ... but those gradient lenses would be terrific for evening rides.
