– Why does everything appear green through night vision means?
In: Technology
Real night vision goggles are effectively a very good low light camera attached to a small screen in the goggles. Early night vision systems used monochrome CRT displays, and green is a common color for CRT displays. Also, the human eye happens to be very good at picking out the color green, while we are less good at red, and worst at blue.
I newer night vision systems can provide the image in whatever color you want, or perhaps even full color. But it has entered the popular imagination that night vision is green, so this is always the color that is used in TV shows and movies.
