These were cheap, so I did not expect much.  But I thought they would be better than the $10 sunglasses at Walmart.  They aren't.  The lenses have many little imperfections in the tinting - look like holes.  Also, they are very heavy - the frames are a metal that I would call "pot metal."  That's the stuff they used to make carburetors out of, back when they made carburetors.  They market these as "sturdy but lightweight."  NOT!  These will go in my SUV as a back-up pair for when I'm desparate.
