Please take a look at my ball python's eye.

Okay so I thought this would disappear after his shed but it hasn't. It's like a white(ish) half moon, thin thing around one side of his eye. Sorry for the red pic but hopefully you can see it. This thing is not on the other eye, just the one. Almost looks like a finger nail shape. Hopefully someone can tell me what it is. Thanks guys.

Looks to me like he may have a retained eye cap. They should discard eye caps with each shed. Here is some info you can read and see if this is the case

Thank you for the input. I hope it will come off still. I wil keep his humidity up and see what happens. Thanks.
