text: First pair ordered from the Prime sale were not authentic.  These WERE BOUGHT FROM AMAZON and not a third party seller.  The first red flag regarding the authenticity of the glasses was the inferior &#34;RB&#34; etching on the right lens.  It was done in such a manner that not only could you feel it, but you could also see it from 5-10 feet away as it looked like the lens was damaged (scratch, etc.).  Authentic &#34;RB&#34; etchings are nearly imperceptible and not something that can be easily seen from several feet away. The second, even larger red flag was the presence of a plastic seam on the top of the frame that was easily felt running across the entire length of the front of the sunglasses as well as down the top side of the arms.  Authentic Ray-Ban's are cut from a single piece of acetate, so there should be no seam on the frames (presence of seam suggests injection molding was used for creation). Everything else regarding the glasses seemed legitimate; eg, the case, cleaning cloth, and other features.<br /><br />I submitted for a replacement, will see what I get in the next couple days.
