Could it be to do with the refractive index of the fluids on the
eye.  I know you can get eye drops which claim to make you eyes
sparkle / go more blue.  Maybe changes the nature or type of fluid
in her eyes, changing the R.I., and thus changing hazel eyes, which
have some blue, to brilliant blue.

Purely supposition of course!  But it must be a very satisfying
thing to watch happen!!
