Here's a pair of Lindberg Acetanium hybrid frames that I bought speculatively but that aren't quite right for me.
You get the best of both worlds with these; the look of Acetate and the temple and nosepad adjustability and flexibility of Titanium frames.
Simply take these to your optician to have prescription lenses made and to have the frames fitted for your face.
Of course they can also be made in to (prescription or otherwise) sunglasses.
Thse are ex-display frames...
