To the best of my knowledge... which may be wrong...

Polycarbonate lenses inherently block UV.

If they're another material, you just have to rely on the manufacturer's representations, regardless of the price of the glasses.

And remember that if you're not wearing wrap-around glasses, then your eyes are still exposed to UV from the sides and possibly the top.


Now, W/R/T polarization, I've heard that not all polarized lenses give the shimmer. But I'm not going to spend a lot of money finding out. Especially since you really can't tell inside a store.
