This may have been brought up before but I'm curious as to what is the deciding factor for Oakley to make or not make a certain lens color in a polarized version. For example, I am looking closely at the Deviation with the ruby iridium lens. While the Deviation line is available as polarized, the polarized option isn't available for the ruby lenses. I, for one, would be happy to pay extra for the polarized ruby iridium. Does anyone have any info or details to this? Thanks.
