Night Vision Device
Sarna News
Overview
A Night Vision Device is a common optical device used for both civilian and military roles. Also known as NVDs they can operate under a number of different principals but produce the same effect of allowing to see clearly in darkness. NVDs do have a number of disadvantages though: depth perception is reduced when looking through a NVD, and the ability to distinguish color requires attaching a sophisticated computer for interpretation, a feature normally not available for the average soldier or civilian.[1]
Most every modern military issues NVD goggles to their soldiers, either attached to their helmet or worn as a headband, when night combat is expected.[1] A Night Vision Scope is a common attachment for weapons, while special night-vision lenses can be attached to other devices such as Video Cameras.
