Thanks for the feedback! I don`t abuse my stuff either so if your sunglasses are standing up well to normal use and you`re happy with the performance - thats good enough for me.
Since the Oakley lenses were not light sensitive - it usually ment packing a case with three sets of lenses. They`re optically excellent but with new technology if I can kill the need for interchangable lenses I`d be happier.
