The Interesting Reason Why Everything Looks Green Through Night Vision Goggles

We’ve all seen the green image of night vision goggles. The electronic eyes that work by boosting the weak night-time vision into something much more powerful are commonly used during wars, when observing wildlife at night or in any other occasion in which when we want to turn darkness into light.

But have you ever wondered why does everything look green when looking through these goggles?

Well, as it turns out, it was intentionally made that way and for a pretty good reason. (the article continues after the ad)

Night vision goggles use a green phosphor because the human eye can differentiate more shades of green than any other color, allowing for greater differentiation of objects in the picture. In addition, it’s easier to look at green screens for long periods than to look at, let’s say, black and white ones (that’s why early computer screens tended to be green). Hence, night vision goggles have their characteristic, eerie green glow.
