text: Good alternative when you compare it to a new pair of Oakley.  The fitment is perfect and easily done.  Lens curvature is perfect without waves on the edges.  I am not so sure about the scratch-resistance as I baby them a lot more than before but I don't think it is anything better or worse than the Oakley OEM as they get scratches easily anyway.<br /><br />If it would have been cheaper, I would give the remaining star.  Overall good product to prolong the life of the Oakley frame.
