"these glasses are light and pretty good. they're my first pair that I bought because I was sick of getting red eyes from mud flicked up. In this regard, they are perfect. They also don't fog up whilst riding (once you stop, that's a whole other story but I can live with it).
I would however, not have given them the rave reviews that they presently have.
The one major thing that they are lacking (probably due to high cost) is multi coating so when I ride at night with the clear lenses, I don't see one set of headlights per car. I see 3. At dusk, I see my eyeballs reflecting off the clear lenses. Multicoating the clear lenses would make this pair of glasses perfect in all pretty much all respects.
The grey lenses are much better because they don't let in as much light. in fact, they're pretty much perfect.
haven't tried the orange yet.
Probably my own fault but they weren't quite what I expected from reading the reviews. that said, they are pretty decent as a first pair."
