Since she's blind, her eyes going blue doesn't have to do with her aggression like it would w/ a seeing snake. The eyes are dulled, so they can't see anything, but not the case with your girl.
Maybe she just wants to be left alone? Snakes are vulnerable during shedding, she's probably seeing you as a predator. My snake trusts me as much as she probably ever will, but in shed I know not to mess with her, she'll bite me if I give her the chance.
