question about sunglasses lenses is...

For me, the most important thing is getting polarized lenses. Light conditions vary, but with polarized lenses, you get the glare blocked ( which is really the important thing ). Polarized lenses cost more, but are worth it. Darker, non-polarized lenses block glare as well, but also block a lot of other light too ( they use the shotgun approach ). You can wear lighter lenses if they are polarized, which lets you wear them in a wider range of light conditions without sacrificing your ability to discern details.

My $0.02 anyway.

I agree, I have prescription sunnies for every day, but I hate training in them, particularilly on the bike.

I own a cheap pair of sunnies that are polorized, but only light tint. They are great. we get really sunny weather, which they are fine for, but on overcast days, I can also still wear them.

Unluss you really need the prescription, just as easy to go without prescription (as I do). Then if I loose them, I don't feel as bummed about it!

Thanks. I go in tomorrow and get to pick out the frame and lenses and will make sure they are "polarized."
