I bought set of black iridium polarized Heater lenses for my frames in the summer of 2007, and before the summer was up I was back in to the shop I bought them through getting warranty service. One of the hooks on the lens was cracked pretty badly, and I felt like there was a risk of them being destroyed. The replacement I received had a much more beveled edge where it interacted with the frame, and I decided to dedicate the lens to the frame and not continually swap it in and out as I had been doing. I took the lens out of the frame today for cleaning and when I was checking the lens up to the light I noticed BOTH hooks are developing cracks. Granted, the lens is 4-5 years old, but I should think it would last 2-3 times that. I plan on taking them to the nearby Vault to see if Oakley will cover me. The lens has one small mark where it took an impact from ricochet a few years ago, but it's immaculate otherwise. My other lenses are all Strikes and appear to be no worse for wear, besides the scratches and marks from not caring for them as well. You think Oakley will have my back on this?
