I own 2 pairs of these sunglasses a total of 6 lenses and twice I got a lense with problems holding the nose piece tight. Lucky one lense was the same as onother set. Now I'll contact Smith and tell them like it is and see if they can get me something back. I like this brand and product. I use Rudy Project and Okley also. In my order from this store I got the blue mirror with the same problem. Let's see if they can exchange it, if not I want my money back. If I had no problem I would give this product 5 stars.
