I'm in SE Florida where the sun can get brutal in the summer. So I start many Summer Saturday rides in the dark so I'm back inside by 11:00 AM. I've tried both non-polarized and polarized, and I prefer the polarized lenses. I also wear prescription polarized and have recently purchased transition- polarized lenses, since I start many rides in the dark. I like this combination the most. The transition-polarized won't dull the sun as much as just polarized lenses when it is super bright outside, but I find it quite adequate. I use a Garmin bike computer and have no problem seeing it when I'm on the bike. If I have a problem seeing the computer when I'm off the bike, I can take a step or two to get closer and see it. I also have not noticed any difference in seeing hazards between the non-polarized and polarized lenses. Maybe there is, but I have not noticed it.
