This is to warn against purchasing fake sunglasses.  With just a few tips on things to look for to be sure you are purchasing quality merchandise.

All Prada, Versace, Dolce & Gabbana, D&G, Bvlgari, Ferragamo, Chanel, Vogue, DKNY and Donna Karan are all manufactured by Luxottica Retail.  All are made in Italy except for D&G and Vogue are made in China.  All will come with a certificate of authenticity except for D&G, Vogue, and DKNY.  If they do not have these features THEY ARE FAKE!!!   Where they are made is listed on the inside arm of the glasses.  Don't be fooled by these sellers making you think they are authentic, check for these things.

Rayban are made by Luxottica Retail.  If they say they are made by Baush & Laumb then they are really old  because Rayban has been manufactured by Luxottica for several years now.  All Raybans are manufactured in Italy.  They too have markings to identify they are authentic.  If it has a glass lens  (ask seller)  then there will be a small RB etched on the outside of the  right lens into the glass.  If they have a plastic lens (again ask seller) there will be the same etching but it will be on the inside of lens.  Rayban Aviators should always come in the bumpy looking case.  Not the typical Rayban black smooth leather case.

I hope this helps some of you to keep from wasting money on fake sunglasses!!!
