Did this movie change the canon on Riddick's eyes?
Based on a Necro quote in this movie about having seen warriors from Furya (or at least one badass Furyan) with the glazed eyes, it less-than-subtly insinuated that Riddick's eyes were a known Furyan trait.
But in Pitch Black, Riddick says in no uncertain terms that he got his eyes 'shined' in prison - so he could see people in the dark trying to kill him or some such - and if memory serves, even went into detail about how it was a risky procedure.
Seems weird they'd change the canon in this movie to be some more mythical trait, even if that observation about Furyans was not confirmed (or denied).
