It’s really creepy when her eyes are that wide open.
That is not normal or natural...
To me that indicates she’s on some strong medicine, but that’s just my opinion. But I can’t think of any other reason for someone’s eyes to be that wide open that the entire iris can be seen.
keep in mind that she wears color-changing contact lenses.
the iris size is whatever she wants it to be
I think it is some mechanism she has been taught to use to try to cope with her eyes acting up. She does other things like when she starts to freeze up she looks down or looks to the side or closes her eyes tightly. I believe others who have experience with Parkinson’s patients have pointed out exercises or things people with Parkinson’s can do to stop when they freeze up for other reactions.
She has mid-stage Parkinson’s. Check out doctors on YouTube and what they are saying.
