Used Oakley XX 24K lens. Light swirling/scratches, still very usable and not noticeable unless you look up close. Nothing visible when being worn either. I got a pair of XX 24K's from a member, but I'm going with custom cut sapphire lenses from IH, and having the frame changed to TiO2. Price is $65.00 shipped, US only please. I ship USPS priority.
