Led Night
how are red LED’s used for night vision?
i just got a new head lamp and it has 3 modes
1 haligoen bulb
1 white led
2 red led
what do the red led’s do? it says for night vision but i don’t get how red led’s help?
Red light doesn’t affect your night vision. You can look right at it and your pupils do not react. White light makes your pupils shrink.
Not sure why, but it is a fact. You can use a red lens on your flashlight also and it won’t affect your vision. Turn the light off and you can see well in the dark.
I used to use a red light when I hiked at night. Let’s you see everything and not be night blind.
