Maybe it could also be to intimidate other predators, as a part of their evolution? The same way as some animals scare others away by making themselves threatening, like the frilled lizard does with it's mantle. Not sure though, but I'd be pretty intimidated if someone came up to me and their sclera suddenly turned black and their iris turned red.
