Sunglasses for the man with a more oblong head

I seem to have a problem finding sunglasses. The lenses are always too long for my face in the sense that they jut outward and seem bulky/awkward. Sports glasses (such as the smaller Oakley flak jacket) work decently because they wrap around the face, but I was looking for a more traditional type pair to go with a suit. So far I have tried on an entire small sunglass hut store to no avail. Ideas?
