Personally, I do. As we know, it is very important to choose a pair of sunglasses that really suit you and match your face shape. No matter what face shape you are having, you can definitely find your own suitable sunglasses. For those who have a round or even big face shape, including me, we'd like to wear bigger sunglasses to cover larger area of our face. Thus, our face would look much smaller and thinner. Therefore, you can also get a pair of bigger sunglass to hide your face and make yourself look thinner and more fashionable.
Different people may wear sunglasses for different purpose. Most people wear sunglasses in order to protect their eyes from harmful UV rays. While fome people wear sunglasses just for fashion purpose. There are some other people who wear sunglasses for hiding their faces. People who have dark circles or some injuries on their faces would wear sunglasses to hide their faces so that nobody will notice them.
In most cases,I don't like wearing sunglasses except in sunny and hot days.I think some people may have a reason for wearing sunglasses in most of time.I guess they may just want to hide their faces so that they will not be recognized by other people.On the other hand,wearing sunglasses can make people hard to make other people tell who u r and in my opinion,everyone looks like a star when he or she wears a pair of sunglasses.
