If you need a pair to fit over regular glasses I (the cheapskate) would recommend a pair from Sprawl Mart that goes for $18.00! I ride a bent with an upright head so don't need to worry about glasses that you have to look high up on the lens. But the lenses in these are very wide angle, polarized, etc. and seem to be adequately impact resistant as I got nailed with a reasonable sized rock in one thrown up by a Kenworth the other day! Scratched the lens, but that's all! For the price they can't be beat!
