I use all my sons hand me downs and he has some fine glasses. Smith, Delmar and some earlier cheap ones from Gander $10 that weren't too bad. He now has Oakleys and I have to tell you I'm waiting for something better to come out so I can have his. They have by far better optics than Smith and Delmar. They aren't cheap so if you take care of your glasses and appreciate good ones I assure you they are worth the $$$'s. I trash mine. drop them and lose them so I fall into the $10 Gander glasses when I can't snatch my sons rejects. Check out Oakleys website they show you visual optics.
