I've been using this blog as a means to keep track of how often we have to replace Lex's glasses.
This past weekend, we had to visit Wal*Mart again to get another warranty replacement pair. The metal frame that holds the lenses in his glasses had separated from the rest of the frame. Again. This must be a flaw with this design. I'm not really concerned about it, though, as they are warranted, and because they just took his lenses out of the old pair and put them into the new frame in under 10 minutes for free.
