I don't know if this will help any of you, but I think I saw an identical pair (or appeared to be) sunglasses at Costco optical the other day. They are not raybans, they are Costco's brand, but they looked the closest to the pair that were posted here that I've seen. They were located in the section on the wall that has sunglasses that can be converted to prescription lenses. I believe you can just buy the frame and get whatever lenses (clear) put in that you want. They were also cheap, I think they were around $60
