I think the lenses on knock-offs can be disappointing. They scratch, aren't clear and don't provide 100% UV protection. I must say, I applaud your taste. For genuine, authentic D&G by Dolce And Gabbana that are brand new and come with the full D&G warranty, see the D&G at OpticsPlanet. We also carry the other prestigious eyewear labels of the Luxottica Group.
