– Why does everything appear green through night vision means?
In: Technology
Depending on your night vision system, it doesn’t.
Night vision goggles that use light amplification take the very low levels of light present and amplify them to be visible light. Limiting the detection system to specific colors (as you’d need to do in order to have a color image) significantly reduces the amount of light it can collect. As such, these NVG’s see in black and white. Then, they display that image for the user, typically in greenscale because our eyes are the most sensitive to green colors.
