This is my third pair of these frames over the years. I found the first at a thrift store, the last two (in tortoise and now black) through Amazon. Each time, I've had opticians replace the lenses with no-line bifocals, and have been very pleased w/ the results. The fairly large size allows for a nice space for the progressive lenses, and I get lots of compliments on them. And, perhaps best of all, I get a very well-made frames, with classic (read:nerd) fashion for a lot less than many opticals shops, as well as a frame that I've NEVER seen on anyone else except on TV or movies.
