Your correct. One more slight difference is the stems are supposed to be a mm smaller as well. I've never noticed the difference. Personally I don't like the Asia fit frames but some prefer them. It just sits too high on my face.Sorry about resurrecting an old thread.
So to clarify. The ONLY differences between Asian fit frogskins and normal frogskins are a slightly adjusted nose bridge and some different colour combos. ie. the arms, curvature of actual frame and lenses (more importantly) are exactly the same.
