I am currently rocking the Dragon Shields Matte Black/ Blue-Ion Polar, these are Mick Fanning signature editions.... Hands down, best shades I have ever owned, and I've owned them all. They come with a scratch resistant coating (among other coatings) that I was really scepticle of, but after seeing them slide numerous times, lense down, on the concrete/ asphalt.... I'm a true believer in this miracle coating.
I have had them about a year, and they are still as clear as the day they were bought. They have a few micro-scratches, I just pulled them off my hat and looked.
I love the lenses also, extremely high def, great in extremely sunny conditions, due to the ion coating. Let the sun go behind the clouds, or let it start to get dark or rainy, and this is where the actual amber lens comes into play..... Best of both worlds......
Maybe there are some others out there with these shades, and can back me up,
