i just purchased a pair of used Oakley Conquest sunglasses that have polarized etched on one lens. My etching says “Polarized”, except in cursive and I have never seen that. I have heard that Oakley has done that in different styles but that it mostly is in block letters and all caps. Does this mean they could be fake? They have everything else that would indicate they are the real deal. Please comment if you have thoughts on this.
