Looking for sunglasses similar to Ray Ban Caravans?

[luke71]

I am going to get a pair of prescription sunglasses. Have had an idea of what I want but have not seen it in any stores here in London and now saw Ray Ban Caravans on a website. Have been wanting aviator style but not the round ones. I already own a pair of prescrition sunnies(sort of rap around) but want a different style.

The Caravans is what I'm after but I'm worried about the thickness of the frame. I need thicker frames.

So Does anyone know of any brands that offer the same shape as the caravans but thicker frames. (A long shot I know but so far this website has really helped me out)

Cheers
