What's the most unique vision based powers you've seen?

Stuff like laser vision is pretty common, but I'm wondering what other kind of abilities could be tied to vision?

Stuff like x-ray vision, 360 perception, maybe seeing the entire light spectrum?

Heimdell in Marvel is supposed to be able to see literally everything but I've never seen it really elaborated on.

Gorgon and the novel EX heroes is able to siphon energy and power from others and wears special goggles to protect others and dial in is abilities, I thought that was a cool example.
