Ive tried a few different brands and always end up going back to Smith, dont get caught up with going with a fishing company or anything like that. As long as you get a reputable brand i.e. smith, oakley, orvis etc. you should be all right. Im a strong believer in not only the quality of the lens when it comes to eyewear but also the fit of the glasses. My suggestion would be to get a couple of recommendations from the guys at your local fly shop and then try them on. Good luck, everyone is gonna have a different opinion when it comes to eyewear.
