Do Rayban provides frameless styles?

[bifocal glasses]

I especially love to wear Rayban aviator style sunglasses, as it is really fashionable and lovely, you know that eyeglasses serve to let the world know just a little bit more about your personality more than just being able to see, you can choose these eye wears not only for ordinary sunglasses, but also Rx, reading and computer eyeglasses, prescription glasses nowadays are as big a fashion accessory as your pendents, shoes and purse, they are not only used for function but also fashion, do Rayban provide frameless styles? I have been to several online sites, but without any results, anyone can give me a piece of advice?
