To me, they are for wearing in rough situations instead of your good ones so you can keep your 200.00 Revos in good shape but since they were a gift to a spoiled teenager that I thought would wear them while playing hockey in order not to ruin his good shades, he gave an unenthusiastic thanks which is more than I got for the hoodie he received from me for a prior occasion.  I vote 4 stars for good quality polarized lenses.  Id buy them again.
