Night Vision Goggles are optical devices that allow users to see in low-light conditions. They work by amplifying available light, including infrared light, to create a visible image. This technology is commonly used by military personnel, law enforcement, and wildlife observers. These goggles typically consist of a lens system, an image intensifier tube, and an eyepiece. The image intensifier tube converts light into electrons, which are then amplified and transformed back into visible light. This enables users to see clearly in darkness, making night vision an essential tool for various applications.
