I have had these for about two months now and can definitively say they are the worst pair of sunglasses I have ever had. The lenses scratch if they touch anything and both sides have started to separate from the frame. This is my first time with Ray-Ban and my last. In all fairness, I have dropped these glasses twice which has resulted in chips and scratches to the lenses. However, the glasses fell from around 3 feet, as I was bending over. So, in my opinion, and from owning Oakley products, these scratch/chip way too easily.
