I think name is enough to describe the quality factor.i am a big fan of ray ban.it makes me more personalted.
No doubt it is expensive but infront of fashion money doesnt matter .it also provides many frames.it is famous for its manufacturing of power glass frames.
It gives funky and cool look to me.as I am student of university it proves very usefull for me as in a way it protects me from sun and in my department it gives me the trendy look. In short I love ray ban the most.
