Great lenses. I had the original Ray ban and the colours were not as natural as they are with these pair of lenses. Unfortunately I managed to have a little scratch in one after one week. I can't tell how it happend but it is my fault I guess. ;-)  PS: It's the 23rd of August 2015. I went to the forrest and accidently dropped my sunglasses. It fell on the soft ground and of course there are a lot of scratches on it. As I know from my original RayBan lenses it did not happen at all and I had them replaced two weeks ago after 5 years. This seems to be a lack of production processes to harden the lenses. I am very dissapointed. So I drop my previous rating from 5 stars to 2. I've realized that the little sratch I've reported may be not my fault too
