At first I wanted to get myself a pair of aviator goggles but they don't fit everyone and their moms who own RayBans and they fit perfectly. I had a pair of polycarbonate lenses and they are much better, the design and the quality of the materials are noticeably better. They also have a finish on the back of the lens that your eyes look through that eliminates glare and specular reflection, which is a really cool and effective feature. Although they are heavy so you can tell the company is using high quality materials, they are very light on your face and I forget I'm wearing them half the time.
