Visably smaller:not a 54mm; more like a 52mm
Unfortunately, the frame is a smaller eye size than advertised. It required me to take the new frame and the existing lenses to my Optometrist for their lab to edge lenses down in order to fit replacement frame. Should have been an exact match. I guess it did not meet quality control from NewYorkNewYork/Esquire and, therefore, sold to a third party...Speert Int'l. Otherwise, the Speert Phone Rep was very helpful/nice to work with!
