BLUE TONGUE SKINKS

Hi all, I'm a new owner of two baby eastern blue tongues. About 1 month old. One of them has had his eye go cloudy. Only the bottom half and after a day or two it cleared up. What would cause this? I'm worried if I'm feeding him too much protein or too much multi vitamin and d3?

He may have gotten some foreign particulate in there, if it cleared up that's all I can think of. Dust particles and whatnot in the substrate, or he could have irritated it rubbing on something. I'd just keep watching it and if it reappears, have it checked out.
