The level of performance for the AN/PVS-14 depends upon the level of:

The level of performance for the AN/PVS-14, which is a monocular night vision device, is primarily influenced by light conditions. This device is designed to amplify available light, including near-infrared light, to produce a visible image in low-light situations. Its effectiveness directly depends on the amount of ambient light present; in well-lit environments, the performance can be optimal, while in darker conditions, the performance may diminish significantly.

In contrast, factors like training and experience relate to how effectively the user can operate the device but do not influence the inherent capabilities of the AN/PVS-14 itself. Additionally, temperature can impact the functioning of electronic devices, including night vision systems, but the core performance—what the device can do under varying lighting conditions—is determined primarily by the available light. Thus, understanding the importance of light is vital for maximizing the potential of the AN/PVS-14 in the field.
