My biggest peeve.. I'm glad others saw this and answered. Definitely never mess with the eyes. That's becoming my motto around here. They fix their selves with humidity, humid hides, and if absolutely necessary (meaning if you do not find the round caps on the head piece after it sheds) a tiny bit of ointment on the eyes every day or every other day.. But only at the beginning of the next shed cycle until it sheds.
The caps (even when not retained) can dent, dry out, wrinkle, and appear cracked if the humidity is low. This does not mean stuck caps. It will always fix itself with the proper conditions.
I wonder how these poor creatures ever survived so long in the wild without the help of humans considering all the droughts that Africa has....
