Straight from a PVS-7 Night Vision Goggle Manual
Here's some text straight from a PVS-7 Night Vision Goggle User's Manual:
EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES
WARNING - EQUIPMENT LIMITATIONS
To avoid physical and equipment damage when using the AN/PVS-7 goggle, carefully read and understand the following safety precautions.
- The equipment requires some night light (moonlight, starlight, etc.,) to operate. The level of performance depends upon the level of light.
- Night light is reduced by passing cloud cover, while operating under trees, in building shadows, etc.
- The equipment is less effective viewing into shadows and other darkened areas.
- The equipment is less effective through rain, fog, sleet, snow or smoke.
- The equipment will not "see" through dense smoke.
- Adjust vehicular speed to prevent overdriving the range of view when conditions of possible reducation or loss of vision exist.
CAUTION:
The AN/PVS-7 is a precision optical instrument and must be handled carefully at all times to prevent damage.
The AN/PVS-7 is a hand-held, headmounted or helmet mounted night vision system that enables walking, driving, weapons firing, short range surveillance, map reading, vehicle maintenance, and administering first aid in both moonlight and starlight. Each unit allows for vertical adjustment (by using head straps), fore-and-aft adjustment, objective lens focus, eyepiece focus, and eye span distance adjustment. The goggles are also equipped with an infrared light-emitting source and a low battery indicator. The goggles automatically shut off when disconnected from the headmount or helmet mount. There is also a high-light cutoff feature that shuts of power to the goggles when they are exposed to high levels of light for 70 (+/- 30) seconds.
I thought it was interesting that it included "vehicle maintenance, map reading, and administering first aid." These are applications for night vision equipment you don't hear about very much.

The first thing that might strike one's mind is that night vision equipment might be a spy thing in an action film. But they are real. There are many instances in which night vision equipment can come in handy. For example, with suitable night vision equipment, one can see a person standing over 200 feet away in complete darkness. This can be useful in many applications and scenarios, such as military use. But personal use is also a popular mode of night vision equipment. Nevertheless, night vision equipment can be utilized to work in two very different ways, depending on the technology that is implemented. Night vision equipment can work in two very different ways, depending on the technology that is implemented. One is image enhancement, and the other is thermal imaging. These are just the two basic types of night vision equipment; there are variations you should check out when making your selection.
