Why are alitas' eyes so big?

I've always wondered, why are alitas' eyes so disproportionately large? Is it a mere aesthetic choice by the creators, or does it serve a deeper purpose in their world? Could it be related to their enhanced vision or some other sensory ability? Or is it simply a way to convey emotion and personality more effectively in their expressive faces? I'd love to hear some insights and theories on this intriguing aspect of the alita character design.
