While focusing on which glasses you want to buy, you often look at the frames and the lenses, quite forgetting that the support lies in the two arms of the sunglasses as well. And that is where the magic lies for these pairs. The alloy metal frame is supported by the serrated edges of a uniquely optimised pair of branches which are designed to sit well on your ears. The lenses are polycarbonate and imbued with properties that can fight the harm of UV rays and are also anti-reflective. The frame and the function is a classic favourite.
