What do all the colours on the torch mean?

I got a torch for my birthday a Gerber torch.It has four colour lenses. On the packet it said that;
The red lens is for not affecting the eyes.
The blue lens is for seeing liquids.
The green one is for map reading
The normal lens is for seeing.

My question is; when i use the red lens so my eyes do not become disorientated (can't think of correct term) it barely shines in front, i mean it really makes very little difference. The torch i small yet when using the plain lens it is as bright as anything.Do the other colours affect the eyes as much? Is the red actually for that purpose because the other lenses are much brighter.
