A question about Ayu's eyes...

[Hok]

Comparing the differences in the sizes of her eyes from recent pictures to yester years, it looked like they have increased in sized. I was wondering if her eyes are natural or have she gotten that surgery thing where they suck the fat out of the eyelids or whatever in order to "open" up the eyes. Even my friend's first impression of her was "she looks white" (as in American eye size).
