Ray-ban is undoubtedly the best brand when it comes to sunglasses fashion accessory. While it is too costly on one hand, it gives you a classy look and is a premium brand.
Aviator model is the best model out of all and I am a fan of that model. It also gives ultra-violet protection against sun to your eyes and has the best in class and quality material used in manufacturing, so they are very durable also, I am using my aviators since two years and it still looks as beautiful as when it was bought. I think it is a style statement for youth and always going to be the best brand in sun glasses. I rate it five out of five.
