Decent glasses if you aren't brand conscious.  I use these as beater glasses when I go biking.  The lens doesn't appear to be optically correct/clear but for the price I wasn't expecting much.

Hidden bonus:  Had a really gnarly bike crash and these glasses were in my pants pocket.  I pulled out a bunch of what I thought were broken parts of the glasses out of my pocket.  Turns out the parts just snap back together and the glasses were again perfectly functional.
