Ray-Ban calls these Erika Classic rb4171 and their list price is $166–189 depending on color. I bought light blue from Woot for $84.99. That was a bit much for me, but they were 54-18-145 which is my size and they fit perfectly. I wanted one pair of prestige shades and that was these, although Ray-Ban is Ray-Ban no more. Bausch & Lomb sold the Ray-Ban name to Luxottica Group in 1999, and this Italian fashion house has “Ray-Ban” built to order in China. Nevertheless they are well made and their sizing is correct. Be aware that they aren’t your father’s Ray-Bans.
