Red-light headlamps are frequently used in outdoor activities like camping, hiking, and hunting because they have a number of benefits over white-light headlamps.
Preserves Night Vision
White light interferes more with your eyes' built-in night vision than red light does. It takes some time for your pupils to adjust back to low light after using white light in low light circumstances because they enlarge to take in more light. Turning off the light makes it simpler to see in the dark because red light doesn't have as much of an impact on your eyes.
In low-light conditions, red light reduces glare and improves contrast. This makes it easier to see distant objects without causing eye strain or discomfort.
Red light can be used to maintain stealth in certain situations, such as hunting or military operations. Because animals, especially nocturnal ones, are less sensitive to red light, it can be used to illuminate your surroundings without waking them up.
