Let me preface this reviewing by saying that I think sunglasses in general are way overpriced for what you actually get.  (It's just a piece of fancy plastic!)  The thought of spending multiple hundreds of dollars for a pair of sunglasses just seems crazy to me.  This set was a compromise.  I generally like the look and feel better than my $20 pair.  The quality of vision is not especially great at least with the black lenses.  (In fairness, I haven't used the additional lenses provided.)  To be honest, I justify this purchase by the fact that it comes with a case that protects the glasses while also holding the 2 additional lenses just in case I ever decide to try switching.  So as I started, these are better than what I was wearing but....
