These glasses feel real sturdy, and the lenses seem good.
However, they didn't quite fit my face.  They felt good around my head (7 1/4 hat size), but they didn't sit on my nose right.  There was a small gap around the bridge of my nose that let light in, so I had bright spot in the middle of my field of vision.
I've returned them, and I'll select another pair of Oakley glasses.  These are made in the US and seem well made.
