2500NV - Night Vision Configuration

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.

Military personnel, SAR, and pilots flying in darkness are often concerned with preserving their night vision. So Kestrel created the 'NV' line to address thsi issue.
