This is my second pair of JFLs and looks like I need to return them again. They have what starts as a crackling pattern on the lens, like you've gone at it with a brillo pad. Have it a gentle run with a bag and it's developed into a thumbprint size mess of swirls, like the coating is just rubbing off. First set did exactly the same and RXsport replaced them. Hugely disappointed really and I don't want a replacement set of Black Iridium again, not sure if they'll let me choose another colour or maybe pay extra for polarised.
