Yes, an explanation would be something like...Kryptonians could naturally see into the infrared, and had evolved organs in the ocular system to store and project infrared radiation to see in otherwise absolute darkness. Their version of echolocation, as it were.
Then, upon hitting Earth, those organs are just as supercharged as their muscles, etc.
How did Superman beat Zod?
To be fair, those were classic Disney Villain Deaths, to the extent that, as a youngster, I did wonder whether the villains were, in fact killed, or if the Fortress was keeping them literally on ice somewhere in its depths.
Zod wanted to die at that point. It was suicide by Superman, or suicide by cop.

Apparently Zod's death wasn't what Richard Donner wanted, and the director's cut shows that Zod's still alive at the bottom of the pit, or something.
But I never saw the director's cut, and I don't see that it matters. In the film as it stood in the clip Morrus posted, Zod is toast. The hand-crush is brutal.
Certainly, and I don't think Superman's killing of Zod in the current movie is wrong, or out-of-character. But there is a difference, perception-wise, between having the villain vanish into a fog-pit to some undefined probably-dead fate, and snapping the villain's neck on screen. I think it's alright to be bothered more by the latter than the former.
Not saying you're wrong (since that's certainly what it looks like in the movie cut), but the TV cut shows "arctic police" or something arresting the lot and taking them away. So I guess that bit was cut from the movie (implying their deaths). I just thought that was interesting.Mainly by people who have clearly forgotten the end of Superman II where he casually executed a powerless Zod and showed no remorse whatsoever.
