Not too bad, but...
They're very lightweight and flexible.  Great reading glasses considering they're weren't prescribed.  Unfortunately, after about a month of daily use, one of the nose pieces fell off--who knows where.  Ever since that happened, they seem to be falling apart bit by bit a little more each day, plus without one nose piece, they're no longer as comfortable.  I'll look elsewhere when the 2nd pair behaves the same way, because I have a feeling they will.
