White ring around eye?

This isn't a picture of Shelby, but one of another Ball Python that I found online just now. With Shelby, there's no visible eye cap over the eye, just that piece around it.

So it looks like that white half ring all around her eye?

Try giving her a room-luke warm soak. Then see if you can rub it off with a damp towel. :]

If it didn't come off with the recent shed, it's probably retaining, and could lead to problems if it keeps building up.
If it's not stuck shed, it could be a scar maybe? I don't know what else.
