Anti-Fog/ Protective Window for PVS-14, requires eyecup retaining ring

The PVS-14 Demist Shield snaps onto the eye piece of the unit to prevent condensation from forming on the optics during rapid temperature changes, heavy and/or long use. This low cost sacrifical lens is cheap insurance to keep your PVS-14 operational in various conditions. Make sure to be mindful of the thin O-Ring that seals the Demist shield with the optic. We recommend this accessory for anyone operating in constantly humid or maritime environments as well as those in desert locations where the temperature can change dramatically between dusk and dawn.
