Reverse Shed???

[tcutting]

I'm a new ball python owner and I've had my girl for about two and a half months. I've done enough research on them to probably write a book, lol, because I wanted to be a prepared proper snake owner.
Anyway, I noticed one day that her eyes has gone all "milky blue" and that she was more than likely going to shed. So I raised her humidity, that I usually keep around 55%-60% to about 70%. I thought that would be fine but a few days later I came back to check on her and here eyes have gone back normal again. And she did not shed... Is is possible to reverse a shed or is this normal?
If Someone could respond that would be SUPER helpful so I should know if I should be freaking out or not.

Right before, like a day before, the shed will go clear again then begin to come off. Not always but i have seen it happen with mine and a few others
