Similar to the origin of most traditional shapes of sunglasses, the square-shaped frame was developed for function rather than aesthetics. Unlike teardrop or round styles, the square has the ability to sit closer to the face, therefore blocking more light that may come in from the top and sides. Pilots prefer this shape not only for the coverage, but because it will fit under their helmet and shield easier. Of course, this flattering shape was adopted and modified many times over by the fashion world and is now seen everywhere. See below to shop Randolph’s square-shaped sunglasses!
