So I'm watching Superman 2...
Why does he squint/turn away from debris?
Zod throws a large concrete object(wall or something) at him. He uses his heat/laser vision to destroy the block. It explodes into rubble. When the rubble flies towards him, he shuts his eyes and turns away. So as not to get it in his eyes.
If he's all bulletproof and whatnot, why does he need to shuts his eyes for some measly little rubble BS??
these are the thoughts that flow through my mind when I'm bored
