Do I need this to make adjustments to my glasses frames? Okay, so I bought some cheap frames from Zenni. I like them a lot, and the fit is pretty good, but not exact. Every time I've had glasses adjusted at the opticians, they've always dipped them in the hot sand pit first. Do I need that? Can I just bend them (they're regular metal frames, not titanium)? Should I not try to do this myself? tag:ask.metafilter.com,2008:site.81071 Tue, 15 Jan 2008 10:48:10 -0800 adjustment glasses handwaving hotsand Caviar
