So I'm getting these:
Yes, they do not appear to have rims. That is because there are not rims around the lenses. Because of the fun involved in making holes in lenses and then sticking screws through the holes, they should be ready Friday or Saturday. Nope, I didn't go to Lenscrafters. seismic recommended a place on O'Farrell: Glitter Optics.
Fairly good prices (not quite as good as Lenscrafters); TERRIFIC selection, and extremely helpful. I'd forgotten what going to a private optometrist's was like.
