Who uses night vision?

The original purpose of night vision was to locate enemy targets at night. It is still used extensively by the military for that purpose, as well as for navigation, surveillance and targeting. Police and security often use both thermal-imaging and image-enhancement technology, particularly for surveillance.

What color is hardest to see at night?

This sensitivity to shorter wavelengths is called the Purkinje shift. Now, given that it’s night time and that your eyes have undergone dark adaptation, it becomes harder to see colors of longer wavelengths courtesy of the Purkinje shift, making it harder to see shades of red at night.
