After I put it to the test, I can say without a doubt, these replacement lenses bring a fresh look to my old Oakley sunglasses. The clarity and polarization are top-notch making each outdoor ACTIVITY a treat for the eyes. The installation was a breeze, taking just a few minutes. Mens Fashion has never been more effortless with these lenses. The only downside is that the price seems a bit high, but the quality is definitely worth the investment..
