And also, you should know that they can provide 100% UVB and UVA rays protection, so they are used wildly by many people who like sport outdoor. Of course, if you are a sports lover, it will be beneficial for you. I will suggest you buy them on online shop, for they are cheaper than the real stores. For example, you can buy them at http://www.amazon.com/Chloe-Sunglasses-2189L-CO4-Brown/dp/B003XEG0LS. They will cost you about 200 dollars. Of course, it all depends on what kind of sunglasses you choose. They are very good for you. And when you buy them, there will come complete with certificate of authenticity, protective case and cleaning cloth. Anyway, just have a try.
