I really lover the style and comfor of these glasses but I dropped them once on a tile floor and they immediately had chips.  Not scratches chips and you can see them in your view like waterspots.  Just don't think the lenses should chip off the reflective material so easy.  I had many $20 glasses that could take more of a beating.  Scratches yes chips no.  Probably wouldn't buy again cause the lenses cost as much as the glasses did on the orginal purchase.
