I like full size sunglasses, they look great, and they provide great protection from sunlight, as well as dust (I wear contacts). The Antix has a good size, big but not too big, great fit all around, not heavy and not too light, and the lens is changable. And I like the all black look, classy, sporty and conservative. I was able to get a polarized lens, and was able to change it by myself (youtube).
Great service and price by Amazon.
