Essentially you are just dimming the light. Same deal with fox hunting with a red light. Just dims it's a little. The red spectrum can't be totally isolated by a filter or light.

From:

human anatomy - Does red light preserve your night vision? - Biology Stack Exchange

I said doesn't kill, not totally preserves. Any artificial light source at night is going to negatively impact your night vision. Red does so to a much lesser degree.
Whereas a yellow or white light leaves you just about blind.

From what I was taught.... red, green or blue.... it doesn't matter that much. All help preserve your night vision because you are using mostly the cones in your eyes for the colours.

By not using white light you are not 'blinding' the rods in your eyes. Rods detect light & dark (shades of grey) which is what we mostly use for night vision.

Mind you, all three colours have their problems when map reading at night:

Red - you can't see the contour lines
Green - you can't see the wooded areas
Blue - you can't see the creeks & rivers

Cheers,

I'm red green colourblind... so not sure if it will work on me

I always wanted one of these torches, never got around to buying one and then LED came out. They still look awesome
