Hoping it's just a camera artifact, but the one photo of your 2nd snake almost looks like a kink about where the ringer would is.
Also I would make sure to keep the humidity up for that one as well. The eye looks like there was maybe some shedding problems last time. Hoping it wasn't a mite problem cause they also like to get into the eye area.
Yes that is just artifact fortunately.
Also we got him from a poor situation where he did have a pretty bad mite infestation, but he’s been quarantined and treated. So far he’s mite free for about two weeks.
