Very good quality sun glasses.  A little bit big for my face as I have a pin head but nevertheless, I like 'em.  The lens that comes installed in the frame is very good.  Vision quality is quite excellent, and I can wear them playing golf which is something I have never been able to do with other sunglasses.  Don't know if I will use the lenses that are included, but they are there if I need them.  Good quality.  Good price.
