+322 Your pupils grow as light decreases, right? So what if in pitch black darkness, our pupil takes over the whole iris(colored part), we'd never be able to tell because we couldn't see a thing, amirite?

But don't they need at least a little light to work? They're meant to be used at night, not in an area with absolutely no light.

You see things because the light is bouncing off of the object. If the room was completely dark, the camera wouldn't be able to see.

science: night vision is unaffected by red light. the night vision goggle uses a weak red light attached to the goggles themselves to create a readable image

Wait, what? What does it mean unaffected by red light, but uses a red light to make a readable image?

our night vision does not read red. the goggles do. they turn it into a visible image
