I bought these RayBans at Amazon about six weeks after having an awful experience purchasing another pair of RayBans from a different seller here at Amazon. So I was a bit skeptical about buying another pair here. But when I discovered that the order would ba handled by Amazon themselves, I said "Well, if there IS a problem, there will not be a 15% restocking fee & a run-around about getting a refund & waiting almost three weeks (and having to send multiple emails) AFTER the seller received my return before getting a refund. So I bought them on special at Amazon & the first sent pair were a bit loose on the arms of the glasses, I exchanged them with no problem & had another pair sent. That took about ten days, which I thought was pretty fast.
The glasses are great. I think they are better than the first pair I bought at Amazon and they were half the price of the first pair I bought.  This pair is really the superior pair.
The glasses are lightweight, and easy to wear for long periods of time.  They are just as good as the polarized glasses.  Many of the times I wear them out, I get compliments. I always tell people to check out Amazon if they know what they want, because the prices are excellent. I also tell them if they buy from other sellers at Amazon, to make sure they read the returns / exchanges policy & read the feedback of the seller and make sure that they can be satisfied with the terms. Without a doubt, I would buy from Amazon again!
