The lens is also something that differentiates this eyewear from others. A polarised lens gives you the distortion effect of a polarized lens. There is a little distortion when you look at it from certain angles, but the effect is really cool when you look at it straight on. You'll see it in the screen shots, but it looks amazing when you're up close.

The black lenses feature an increased contrast level of blacks. The black Pit Vipers background allows you to read the text better when reading on a computer or when you're outdoors. On the other hand, the white frame and lens are attractive and give you a sense of space. How about Pit Viper sunglasses with different colored lenses for even more variation?
