I have a pair of TAG Heuer Curves 2S photochromatic sunglasses. They have an awesome wrap design that fits my head very nicely, and the lenses change without me even noticing. I have only had issues with them when it comes to when it gets very cloudy in that they do not get light enough, that and when it has been raining the water can condense and gather on the lens. The case is pretty good too, has a hard section to protect the lenses and a softer section for the rest of it.
