It should not be "squinting it's eyes." I've only seen adults do this when trying to aestivate. Another thing to consider is in many animals, too much heat can and will cause neurological problems. How are you reading the temps? For me, I've stopped using UTH's (during the summer) because it makes the enclosures too hot.

Edit; How it's behaving is not normal.
