Pretty good site about the subject.
I could argue the subject but I'm tired right now. This subject has been paddled abck and forth between sides and it's pretty much all up to you to make your own decision on the matter. Obviously no one's going to know for sure unless someone who is undoubtedly in the know how of such a thing says so, it all depends on where your convictions are strongest. IE: I'm pretty sure she had some cosmestic surgery, a good number of the people on this board do not share this belief *shrug*
As far as "American Eye Size" I think Hok Wai Blue meant the more open, rounder eyes commonly associated to those of European descent as opposed to the Asian epicanthal fold.
