1. Night vision binoculars work with image-intensifier tubes. Surrounding ambient light is collected through the binoculars' lenses and altered in the tubes to create a picture visible to the human eye.
2. Night vision binoculars work in one of two ways. Thermal imaging uses the heat emitted by objects to create a thermal picture. Image enhancement collects all visible and invisible ambient light and amplifies it.
3. In addition to two eyepieces, night vision binoculars feature two objective lenses that allow for stereoscopic vision and depth perception.
4. The primary function of night vision binoculars is seeing with clarity in low-light conditions, not necessarily seeing crisp images at long-range distances.
5. Some binoculars models are designed for both day and night use. These are especially good for camping, as well as bird watching and hunting at dusk and dawn.
6. Generation 1 night vision binoculars are great for novices or for casual uses like boating or camping. They are lighter in weight and less expensive than Generation 2 and 3 binoculars.
7. Generation 2 and 3 night vision binoculars are considerably more expensive than Gen 1 binoculars. However, their advanced technology offers a much brighter image with far less distortion.
8. Along with hunting and nature-watching, night vision binoculars are often used for law enforcement or military purposes. However, they are also useful in areas you may not consider, like assisting helicopter pilots in flight, curbing piracy in movie theaters, and photo and film development.
9. Most night vision binoculars are made to withstand adverse weather conditions like heavy fog or rain, and some can even hold up under total immersion.
10. If you are planning to use your night vision binoculars for hunting purposes, be sure to carefully review all state laws. Regulations and restrictions vary from state to state.
