She always seems to use it as eyes, even in her other forms (including when she's a seal during The Call), and she almost always addresses others like it's her head, but since she's a blob person I'm not sure you can really call it an eye, I'd think it's more of a general purpose sensory organ that covers all the senses, or at least whatever senses she has
She has taken a direct punch to the eye before, and it might've given Terry an extra second before he got tossed around again, she doesn't sound like she's bothered by it, hell it even breaks into globs and slides back into her body like it's nothing
Maybe if you shone a very powerful light at her, maybe she'd flinch, or you'd get a dilation effect similar to how a regular eye dilates
