Well, they're cheap UV400 sunglasses with yellow lenses. Great for driving @ night or just wearing them when it's a bit darker. Not very good to wear in direct sunlight imho, I prefer darker lenses in daylight. Build quality is better than any cheap sumglasses of this "rayban" -model I have seen. They are flexible but sturdy too, a bit hard to explain. Lensen are good, no distortion I could notice. They are only $3 shipped but feel like $30 sunglasses.
