Chromapop eh? Its a tough technology to sell as, when you put on the sunglasses you dont really notice a big change. You can see clearly, colors look good, and you can stare at the sun, same as most other sunglasses out there... so whats the big deal?
I first noticed how good the lens was when I was out on the water fishing. First off, the polarization is great, it takes care of all glare which helps with eye fatigue and seeing "through" the water. The chromapop really shines trying to spot fish. Colors stay true with chromapop and with that, i was able to pick out contrast extremely easily. Fish that I usually wouldnt see until I walked on / spooked them, were clear as day.
If you really want to be impressed with the sunglasses, wear an old pair of sunglasses for 2 minutes then switch to the chromapops. The difference is clearly noticeable. The colors are so much more vibrant and true.
Beyond the crazy lens, the mastermind is a great frame. It has a similar style to Oakleys "holbrook" which has been a top seller for years. They are comfortable and, with the rubber backing to the arms, they dont slip/move around / fall into the river.
