I thought would spray a bit about this company as they have the most kick ass warrantee policy ever. Shades are guaranteed for life, INCLUDING SCRATCHED LENSES. As long as they have not been lost, they will replace them. I had a pair get chewed by a dog. The lenses were gonners although the frames were barely touched. Two weeks after I sent them off I got a brand new pair of shades. The $20 check to cover the processing fee (manufacturer defects do not require this, only scratches) was also returned with the new shades. If you are hard on your sunglasses check them out.
