It's old dead skin. Just like with a stuck scrap of shed leftover that turns all grey and crinkly looking, so won't the eye cap. They are just clear skin is all. I would almost bet the stress of having it on will initiate another repeated shed in a week or so. Unless you're really talented at removing them and have lots of experience doing it, I don't suggest anyone (vets included) touching them. Like I said already- there is way more danger in messing with them then waiting for the next shed to take care of it the easy way. Just make sure you bump the humidity up extra so as to make it softer and come off easier.
