Why do night vision goggles see green at night? In fact, it is not completely green. Digital night vision devices actually see black and white targets, while low-light night vision devices are mostly green.

In fact, traditional night vision devices have tried many other colors before designing the confirmed colors, and finally found that the green effect is the best, and it is easier to perceive the image.What’s more, because the eye is most sensitive to light wavelengths near 555 nanometers - that is, green - the display can be a little dimmer, which conserves battery power.
