As usual Foschi Exotic Serpents has it right. I'll add that having some polysporin on hand is a good idea. I'd not use it on a stuck eye cap unless it was multiple. Just wait the snake will not be bothered by it and just spend that effort (rather than worrying about it) working on humidity and finding a method of raising it. A humid hide is a good method. Larger water bowl, a mister (remember pressure misters are finer and basically work better...)

This one is awesome it is super fine almost as fine as a fogger.
This isn't a big concern do not worry about it and just try to get the humidity up to the mid 50s low 60s and it will correct itself.
