B's new glasses

B recently bought two new pairs of glasses online to replace the ones (well, two pairs that are identical) he's had forever. The ones on the bottom are indestructible. One of the pannier bags on his new bike fell off while he was riding and got run over by a car. All that was in the bag were these glasses in a case. The one arm is a little tweaked. And if you look through them closely you can see some stress lines in the lens from having been run over. But they still work. And they didn't cost us a billion dollars. He bought them online because they were cheaper than elsewhere.
