Why Do Flashlights Have a Green Light?

Before green, red was the general-purpose filter that was widely used.

But the red color could be detected easily by the other side becoming a problem for military personnel to go into stealth mode and could also be detected by animals, hence hunting became difficult and hiking dangerous.

The green light has higher contrast, makes it easier to see for the human eyes, and does not scare off any deers or fishes.

In addition to that, green light won’t be confused as a signal for “help” and in many cases, is great to preserve night vision as it requires less brightness for the same amount of illumination.

As most of the animals were dichromatic and couldn’t detect green color, it became the most preferred color for the hunting and hiking flashlights.

Furthermore, as the green color scatters more, many astronomers prefer green-colored lenses to point out and look at constellations in the sky.

Flashlight with Red Light vs with Green Light, Which Is Better for Night Vision?

This one is mostly a matter of preferences. If the main goal is to preserve night vision, red light is the winner.

For example, people who hike during the night times would need to look at maps and reading instruments, need distance vision, and would surely want they don’t come off as a sign of danger to the animals who will attack them immediately.
