[ELI5] Why is night vision green ?
In: 12
they could make it any color, but they use green because the human eye is most sensitive to the color green.
it works similar to how an old style television works. the image is converted to electrons, which hit a glass lens covered in “phosphor” which is a substance that glows when struck by electrons. the inner surface of old televisions was coated with a similar substance. There are many different phosphors, that can produce many different colors.
