Hi. Just purchased some black racing jackets with prescription lenses , great for everyday use without being too "loud" unlike some colour combos.I have since learned that these have been discontinued. Question is , what support do oakley have for discontinued glasses. Do I have to break the bank buying several sets of rx lenses while they are still available, or should I still be able to buy lenses several years down the line? Also does anyone know what colours are available in rx.thanks
