Eye blister?

I mentioned this in my last post, but I've managed to get a better pic of what appears to be a blister on my veiled's eye. It doesn't seem to be getting bigger or smaller...

It that a blister? From the picture it looks like a piece of shed.

I thought that at first too. It's definitely blistery looking, and has been there for about 2 weeks
