The red filter protects your night vision. Under low-light or no-light conditions using white light can impair your night vision for up to a full hour. Using a red-lens drops the affects of this down considerably normally taking only a few minutes to re-adjust.

The Blue Filter is used primarily for tracking blood. Blood will "glow" under blue light and allows hunters/military/forensics to track trails of blood.

The Green Filter is used when you need more light but don't want others seeing you as easily. Green difusses much quicker than the other colors so it is not as easy to see from a distance.
