Hey guys... I have a few questions regarding Ray Bans (specifically Wayfarers). One, is it possible to separately purchase and put in polarized lenses? I was looking at ones in "black rubber" and they don't come polarized, so wonder how much it'd cost to make an upgrade. However, if I decide against that, I'll just be getting them in regular black and I founds these at J.Crew: http://www.jcrew.com/mens_category/accessories/eyewear/PRDOVR~52148/52148.jsp It seems like a damn good price, especially considering they also mention G15 (polarized) lenses? Is this to good to be true? Does anyone know? Since the seemingly same sunglasses at Rayban.com cost $169 (RB2312, black, G15XLT lens)... http://www.ray-ban.com/usa/sunglass...gleBase-_-GoogleBase-_-GoogleBase-_-RB2132-37 Any help appreciated. Thanks!
