Crested Gecko Eye Problem?

[JoKe]

Hey everyone, I’m new to the forum, just hopping on to ask a question.
I was cleaning my crested gecko’s enclosure today and noticed this abnormality in one of his eyes.
It looks like his pupil has somehow expanded or broken somehow as it is rectangle instead of the regular sharp ovalish shape I normally see. From what I can see, he has no problem dilating or retracting the pupil.
Has anyone seen this before or have a theory as to what is wrong?
Thanks!

I'm not a vet but I'm guessing it's within the normal range of how an eye can look.
