I've long used Oakley Sutro Lite glasses and I needed to replace them. These have outdone the Sutros in terms of the fit and clarity of the optics. There is a slight distortion around the nose, but you quickly adapt. Arms of the frames fit better into my helmet than the Sutro. My only complaint is that these do let a bit more wind in at 35+mph than the Sutros. All in all, a great deal, especially since these are ~half the price of the other Encoders
