What is the primary purpose of Night Vision Goggles (NVGs)?

The primary purpose of Night Vision Goggles (NVGs) is to enhance visibility in low-light conditions by amplifying available light. NVGs work by capturing photons present in low-light environments, such as moonlight or starlight, and amplifying them thousands of times to create a visible image. This technology is crucial for various applications, including military operations, search and rescue missions, and law enforcement, where visibility is compromised due to darkness.

While other options may reference abilities or features of technology, they do not accurately describe the primary function of NVGs. For example, NVGs do not provide a heads-up display; instead, they focus on improving vision through light amplification. Similarly, they do not create 3D images or enable long-distance vision in daylight, as their effectiveness is specifically tailored for low-light environments rather than bright conditions.
