Blue tongue seems to always be closing her eyes?

[Hlark]

Hi guys,
I’m new to this platform! But I just wanted to ask a question regarding my blue tongue’s eyes. Her name is Zeus and she’s about 11 or 12 years old and she’s a little eastern. However I seem to notice she closes her eyes a lot? Like moving around her tank she’ll close her eyes however she can still open both of them and she does when I pick her up, I was just wondering if this was normal? Eating is all normal and she’s really active and alert. The substrate is a mix of sugar cane mulch and Critters Comfort Coarse Organic Coco Reptile Bed, also no sign of swelling or discharge.

I’m not sure if I’m being dramatic however we’ve had issues with respiratory infections in the past so I just want to cautious.

Kind regards

Is it possible that as a comfortable adult she just able to relax while out in the open? If there's no sign of discomfort and she isn't struggling to open her eyes I feel like I wouldn't worry.
