I need to find some good eye protection for trimming. Last year I bought some motorcycle glasses that had a foam insert. They were good but as soon as you get a little scratch on the lens, it becomes hard to see out of them. I need something that is scratch resistant, or something that the tint isn't just a film over the top... something that the lens is tinted all the way through. I've heard of people wearing the Costa Del Mar's. I went to the Bass Pro and tried some on. I liked the Man o war model with 580 glass lens. I am very skeptical about the glass lens but from the reviews I've seen, people have no issue. When they scratch, you can still see out of them. I would imagine the polycarbonate lenses are scratch proof as well. If anyone has used them, please chime in. I need some persuasion towards a good pair of sunglasses or safety glasses.
