Boys Sunglasses
Just like so many other accessories, sunglasses were originally invented to serve a very specific health purpose. They are made to keep the sun out of your eyes when you're working outside. We've known for a long time that direct sunlight in the eyes can cause blindness and other serious problems, so sunglasses were invented to remedy that problem.
But just like so many other things, sunglasses have evolved from simply being a form of eye protection to being a form of fashion. Today you can find sunglasses in all kinds of shapes, sizes and colors. In America, motorcycle police officers are known for their big, round and wide sunglasses that cover half of their face. Other people prefer small, rectangular sunglasses that look as un-natural as they do fashionable.
You can even find different colored lenses for sunglasses. For example, if I was wearing orange shoes, black pants and an orange shirt, I could get orange-tinted sunglass lenses so my entire outfit would match my sunglasses.
