How Do Night Vision Goggles Work? 👁️

Morning SEAL Team 6!

You know, in those movies, where they’re in a pitch black room like this:

And then they whip out the night vision goggles.

Suddenly they can see EVERYTHING, just in green…

Apparently, with some good night vision goggles, you should be able to see a person standing over 600 FEET AWAY!

Pretty cool…

But how do these goggles actually work?

Well, normal vision works cause photons (AKA little light particles) bounce off of things and into your eye.

Like this:

Night vision goggles work in the exact same way just with WAY fewer photons.

Night vision goggles actually act kinda like magnifying glasses.

But instead of magnifying the SIZE, they magnify the brightness.

Lemme explain it like this:

You’ve got a couple photons coming in through the lens of the goggles.

The lens captures and focuses that light onto something called a photo cathode.

Which somehow, through some fancy science, transforms those photons into electrons!

Then these electrons pass through another layer where they go through another fancy sciency process that drastically MULTIPLIES their numbers…

And finally ALL these many, many, electrons pass through ANOTHER layer that turns them back into photons.

And makes them appear green.

Why the green?

Well, because we picked that color!

See, for some reason humans can distinguish greens better than any other color, making it the number 1 best color to… see in the dark!
