I think it is important to truly recognize these above frames. In my mind, they are deemed the fantastic four of sunglasses. Behold, four of the most iconic Vintage Sunglasses to ever exist. These four Vintage Porscher Carrera Sunglasses by Optyl were game changers. One fold, the other inter changes, another wraps, while the last one changed the ski game forever. It is very important to know your history. Keep these frames in mind when looking at new sunglasses, you may see some designers today really don't think for themselves!
