The PVS-14 is designed to be the all around best multi functional night vision monocular available. Head or helmet mounted, the PVS-14 from Night Vision Devices allows the user to retain their night adapted vision in one eye while viewing their surroundings through the illuminated eyepiece of the PVS-14. Another strong ability is for the system to be weapon mounted behind most collimated daylight aimers and Reflex sights such as the ACOG, Aimpoint, and EO Tech systems. This allows the user the ability to use their PVS-14 both as a night vision monocular for increased mobility and tactical awareness and as a short-range weapon sight.
