I actually much prefer the NON-polarized lenses. I have a pair of Natives that are polarized, and it creates some bizarre artifacts on things like manholes or other slightly textured profiles that I don't like. I've never noticed any increased effect for cycling with polarization. If I were fishing or maybe even shooting, I'd probably find great value in it, but not on the bike.
I usually ride at night after work. I get a lot of glare off of car windows and chrome. Polarized minimizes the blinding glare for me.
