I started using Ray-Ban folding wayfarers over 20 years ago and haven't used anything else since. The folding design is great for being able to carry and stash them more easily, and it seems to make the frames less likely to suffer some of the types of damage that glasses with fewer points of flexibility are likely to suffer. The folding design seems to make them fit around a head more comfortably, too. The folding frames are especially great for hiking and backpacking, but they do just fine anywhere else, too. The relatively large lenses are superb for keeping sun, wind, and grit out of your eyes, and they're large enough to protect most peripheral vision. I've used both polarized and regular lenses and like both. Regular lenses are a bit easier to keep clean, but there's no question that polarizing brings out depth, color, and detail in sky, clouds, water, and reflecting surfaces that regular lenses can't. For driving or being around water in sunny conditions, polarized lenses are unbeatable. The pair I ordered came from Sunglass Express: they arrived quickly, in perfect condition, and were a very good price.
