Yep, looks like your bp is shedding. Bump up the humidity to about 70 and you should have a perfect shed. Also, a good way to tell if you bp is going to shed, is to look for the pink/rose belly.
Also expect it to be either cranky or lethargic until he does, and be prepared that he will clear up BEFORE he sheds. Don't panic if his eyes are clear but you dont' see the shed skin.

I have also found that my BP likes to hide for a about a 1-1.5 weeks before she gets to that place where her eyes turn. Otherwise she is out often to say hello.
