What is the purpose of using night vision goggles?

The purpose of using night vision goggles is to amplify available light in low-light conditions, which is why this is the correct answer. Night vision technology works primarily by capturing the minimal light present, even if it is just starlight or moonlight, and then enhancing this light so that images can be seen clearly in the dark. This amplification process allows users to detect objects, navigate environments, and maintain situational awareness during nighttime operations or in low-light situations.

Using night vision goggles does not involve enhancing color vision, as NVGs typically render colors differently or even in shades of green, which is chosen for better visual acuity in low light. Additionally, while NVGs significantly improve visibility in dark environments, they do not allow sight in complete darkness where there is absolutely no light present. Lastly, night vision goggles are not intended to replace traditional goggles but rather to serve a specific purpose suited for low-light scenarios.
