I don't think they are defected. I think it's just a moisture glass issue thing. I'm a woman, so it annoys me pretty bad!! So I'm not sure what I am going to do. I like them better than Oakley. But I come from Polarized Oakley's. I am not sure why they are doing this. Does anyone else's 580 Glass lens (blue) do this? I get moisture in the top left, but sometimes they'll both completely fog up depending on the temp.
