I had a pair of glasses that had some issues. I sent them back for warranty and the decided to replace them but that model was discontinued so I picked out a new pair. They showed up today, I tried them on and there too wide for my face. So back in the box they went.

Strangely enough I have another pair of very lightly used glasses I'd sell if someone is interested, I just dont use them. There called the Smith Interlock 01. They have a polarized light gray lens with a black frame. There used but there are no scratches or signs of wear on these. $60
These ones are discontinued but this is what they look like.
