Luxotica(Lenscrafters) is the #1 optical shop in U.S, with ECCA(eyemasters, etc etc) trailing in 2nd.
they carry kickass brand name design frames. In terms of lenses, If you know what you are looking for, you can find the same material lenses in almost any other optical store.
I would say go to lens crafters, and tell them about your prescription, and let them tell you exactly what type of lenses and coatings they reccommend, and then go somewhere else to find the same thing at a cheaper price if possible. ask about warranty too.
