What safety feature is often included in NVGs to protect against bright lights?

Automatic brightness control (ABC) is a critical safety feature in night vision goggles designed to protect the user’s eyes from sudden bursts of bright light. When NVGs are exposed to intense light sources, such as headlights or other strong illumination, the ABC system automatically adjusts the amplification level of the image intensifier tube. This rapid adjustment helps prevent damage to the sensitive components of the NVGs and minimizes the risk of temporary blindness for the user by swiftly compensating for the bright light exposure.

While brightness filters might reduce the overall intensity of incoming light, and manual brightness control allows the user to adjust settings manually, these options do not provide the immediate response that ABC does. The color adjustment feature does not play a role in light exposure safety, as it primarily affects how colors are perceived through the goggles rather than protecting against bright lights.
