ELI5:why does night vision use the color green?
gpt
So the easy answer for ELi5 is black and white is turned green because the eyes are more sensitive to green. 

Next level is the night vision captures all incoming light over many light wave and make it black and white. To aid further in light magnification they made is green to reduce eye strain  and easy for your eyes to see.

There is a more scientific and deeper engeering reasons but for an ELI5 is for easy of seeing the objects out there.
