Aviators, astronomers, truck drivers, campers and anyone wanting to retain their night vision can benefit from LED flashlights with red or green light options.
Which is best, green or red light? Well, it’s the total brightness of the light that has the most significant effect on night vision retention, so you’ll want a light that allows you to easily adjust brightness. Our eyes are more sensitive to green light, which means you need much less green light than red light to see something, giving green light an edge. See a detailed discussion of this topic here or here.
