ive been searching for prices on racing jacket rx lenses, ageing eyesight is to blame, ive got the black iridium, and like it, eventually ill do my x-metals too, but searching around, lenses are really pricey with progressive and polarized options, some that come up in the search are generic, and I want to stay with the Oakley produced lens, my best price is 311. for single vision, 495. progressive, both polarized, is there any suppliers that discount the rx lenses?
