I have some inexpensive cycling glasses (Tifosi?) with the interchangeable lenses. I rarely use them. They seem bulky on my face and don't fold flat to fit neatly in a pocket. I'm too much of a klutz to properly stick them in my helmet. Plus I'm too Fred-ish for that pro look. I generally wear Ray Bans with an amber tint. My favorites were some wire frame, round lens "Blind Boy Bluesman" style. Sadly they didn't survive a crash and took a chunk of my cheek on the way out.
