Any sites that I can import a frame from or know if in the UK do they prepare the frames in any of the high street opticians?

I need a new pair of glasses and I'm to put it bluntly, fucking annoyed of having such a limited choice of normal european fit glasses that fall down my face constantly.

That's the problem. Asian parents, so I have high cheek bones and flatter nose bridge. I can't find a pair of glasses that look right that don't fall off my face constantly.
