Sunglasses are currently provided in many types according to functional and style classification approaches. Evaluating frame shape, there are square sunglasses, round sunglasses, rectangle sunglasses and so forth. What is the reason for the existence of those differently shaped sunglasses? One possible explanation is that the classification in terms of sunwear frame shape can diversify customers’ demands for sunglass styles. This is similar to the practice in prescription eyeglasses. Sunglasses are a necessary accessory for millions of people around the world. It is a disaster if all of them have the access to only one frame shape. Another explanation is probably the guideline that the frame shape should contrast with the wearer’s face shape. Human beings have different facial shapes like round, square, oval, oblong and triangles. These different face shapes require specific complementary frame shapes while using sunglasses or eyeglasses. It is for sure that not all people will get equally satisfied with a uniform frame shape.
