When a pet snake sheds, ALWAYS check the shed for the eye-caps (to be sure they came off ok), also the tail tip (several missed sheds can result in the death
of tissue & loss of the tail tip, because the old skin constricts the blood flow from reaching the tip adequately).

I agree with Dianne- I cannot tell if it's just a dehydrated & crinkled eye, or a retained eye-cap...and please don't try to remove it (other than encouraging more
humidity by soaking & raising the cage humidity). It's best to have an experienced herp-vet check the eye if a stuck-on eye-cap needs removal...some keepers
have mistakenly tried to remove what turned out NOT to be a retained eye-cap, with severe damage (& blindness) to the snake's eye. It's a job for a professional.
