The glaze over you are talking about will come the day before (or so) he/she sheds. It's more of a fogging of the eyes. The eyes will cloud over and then go away, usually, and then the next day (give or take) he/she will shed. If the shed doesn't come off in one peice, which isn't unordinary in balls for their first few sheds, then either soak him/her in a plastic small tub half way up it's body, with a lid so he/she can't get out, in warm water. Or you can take a pillow case and soak it with warm water and put the snake inside and then place him/her over it's warm end for an hour or so.
