I have a theory to why Nimueh's eyes didn't glow while in use of magic. Okay, since Nimueh was around in the time of the Great Purge she must be very old! But she looks like she is 25! So she's probably doing a spell on herself to change her appearance. And maybe that has tampered with her eyes so they don't glow when using magic? - just a theory!
