If you are looking for the best sunglasses for men in 2013, I strongly suggest you to wear the ray ban sunglasses which will be unique at both the design and the quality. As the big brand which owns the long history, you could get the high quality which you should put the great relax. The quality is so excellent which could let you wear for more than several years. The most attractive side of ray ban sunglasses is the cool appearance which makes the wearer look so cool and different. That is why a lot of men like to wear the ray ban sunglasses. You could take this into consideration although there are many other big brands of sunglasses.
Most of the celebrated brands have newly launched sunglasses for spring 2013.For men, I think Dior may be the best choice. They design the sunglasses with simple, brief frame. And this season they do make some changes with the color, they have more choices for you to choose.
In a word, you can be cool, steady and fashion with Dior sunglasses.
But I still suggest you to go to shopping mall to have a look, and choose the suitable one for yourself.
Ok, from what you said, I know you are quite a man who cares about fashion and what is hot . Anyway, this depends on your personal taste and what attracts you most. However, in 2013, or late 2012, some aviator sunglasses are quite popular throughout America, but they are really different from what they used to be, they are more fashionable and cool, where you could see more new spots. Here is a link for you
You can have a look on the internet to see whether you like them or not. If this kind of sunglasses doesn't go well with your face shape, you can choose another kind of sunglasses. I like framed plastic sunglasses recently. They are very cheap and in fashion now. You can have a try too.
