What is the difference between military binoculars and civilian binoculars?

Many friends who want to buy binoculars must be entangled. They want to buy a good binoculars but the price is not cheap, so they will definitely think twice. If they hear that military binoculars are good, but they lack the knowledge of binoculars, they cannot distinguish between good/bad and true/false.

In fact, there are many differences between military and civilian use according to the use environment and observation objects.
First, their optical systems are different. Most military binoculars have a reticle, and the reticle used at night is also illuminated with lights. The exit pupil distance of military telescopes is relatively large, so that observers can wear gas masks. In order to prevent hitting the head when shooting, some scopes have a pupil exit distance as large as 70 to 80 mm, and are also equipped with soft and hard eye masks and forehead protection.

In terms of optical performance and structural performance, military binoculars are better and more reliable, because their design is more prudent, with high-quality materials and sophisticated craftsmanship, such as good image quality, less stray light, and matching magnification with the size of the exit pupil. The shell of military binoculars is made of metal instead of plastic to ensure that it will not crack or deform after long-term use. In comparison, ordinary civilian binoculars are inferior in terms of sealing and materials. Some not only have plastic shells, but even the inner lenses are also made of plastic.
Due to high quality requirements, military binoculars must undergo environmental tests before leaving the factory, generally including vibration tests, high temperature (+55°C) tests, low temperature (-45°C) tests, rain or water immersion tests, and airtight tests. After these tests, the product performance can still be guaranteed to be within the specified range before leaving the factory. Some products have a built-in dryer in the lens body. The air is pumped out before leaving the factory and then filled with dry air or nitrogen, which can effectively prevent the internal lens from mold and fog in the future. Ordinary civilian binoculars generally do not do environmental tests, or only do part of the tests. This is difficult for people to understand from the market, and it cannot be seen only from the appearance of the product.
Because of these differences, military binoculars are much more expensive to design and manufacture, and therefore priced more than ordinary civilian binoculars.

If you only use it for sailing, hunting, camping, hiking and other outdoor activities, the optical effect of civilian binoculars can already bring excellent visual effects.
