Eye problems or just shedding?

[Bogertophis]

Shedding in snakes is often misunderstood- first off, there is no schedule to it- when they grow, they shed- and growth requires food, warmth & time.

A snake's eyes (as well as their body) will "cloud up" (bluish or milky gray), then they go back to "clear" (looking pretty normal), sometimes for days before they actually shed. This is because their body secretes some moisture between the old & new skin to assist the removal of the old skin- that moisture is what makes the old skin look "clear" so you're seeing their colors more truly, BUT they haven't actually shed yet. Best to keep their humidity up some & be patient.

Also: most snakes will refuse to eat while in a shed cycle, but some will accept food anyway. IMO it's best to skip feeding a snake if you know it's in shed, because both shedding and digesting requires good hydration from the snake's body. If you feed them during shed, sometimes it really messes up their shedding since they cannot do both very well simultaneously- their shed may end up stuck on, coming off in pieces...OR, they barf up their meal, which is even worse. Or that meal will just make the entire process of shedding & digesting take longer. Some snakes can "multi-task" just fine, but it's better not to push food on them...they would not be eating during their shed if they were living in the wild anyway- a little fasting is quite normal for them.
