They've done stuff to her eyes because of the character she plays. At the beginning of the season (three/four weeks ago) she was a baby and in that first episode we saw her grow to teenager in hours or something. But each time she was shown, her eyes were that freaky color. I think it's because of the whole fire-thing the beings that created her/hand a hand in creating her seem to be fond of. The eyes have previously really freaked me out because they were really subtly done.

She does look very pretty. I'm looking forward to seeing her in something different.
