The Kestrel 3500NV was improved to be even more suitable for night-time activities. The Kestrel® NV units are olive drab with a visible red backlight, which helps sustain the user's natural night vision. Military personnel and pilots flying in darkness are often concerend with preserving their night vision.
It takes 30 to 45 minutes for the average eye to adapt to darkness and maximize night vision. Even a short burst of white, yellow, green or blue light "bleaches out" the rod cell photoreceptors in the eye and causes night blindness until the entire adaptation process can take place again. Light in the red spectrum does not cause this "bleaching out", preventing night blindness and night vision fatigue. The units' red backlight is also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations.
