That's what bothered me the most. We were riding by the water, so there was some high glare, and I put my cheepo glasses on. Then we'd move into the shade and I couldn't see a d*** thing. I just bought some Native glasses at Paragon (the apparently across the board overpriced sports shop) for $100, but I don't know if I'll keep them. They have "polarized" lenses, that the people swear are essential for cutting glare. Is that really necessary, do you think? I found Tifori Quam glasses for about $30 online. I'm a little wary about buying a pair I can't try on first, but other than that, will I really notice the difference with the "polarized lenses". The Tifori glasses have alternate lenses that you can change. Will I really need that?
