Radians Vengeance Safety Glasses with Black Frame and Smoke Polarized Lens

I love that these wrap around, which keeps the wind from making my eyes tear up. That same feature though also lets them steam up a bit inside until they get up to body temp. I like that they came with the Chums-type glasses "leash" - they just can hang around my neck until I need to wear them. Handy to have them always nearby this way.

I wrote the 5 star review below (JTM). These polarized glasses have 2 pretty major flaws.
1) When the glasses are folded shut, the back of the ear piece will scratch the polarized lens.
2) After time, the polarized lenses "crack". The lens is intact, but the polarization creates a crackle effect that makes the glasses unusable.

I would NOT purchase again.
