Today, I will talk to you about the correct use skills and maintenance precautions of night vision goggles, as well as some common questions and answers.
The function of night vision goggles:
The function of night vision goggles is to amplify residual light in extremely weak or completely dark environments to improve human vision. Therefore, night vision goggles are very important for many occasions where activities need to be carried out in dark environments.
What types of night vision goggles are available on the market?
According to the working principle, night vision goggles can be divided into active night vision goggles and passive night vision goggles.

(1) Active night vision goggles emit invisible infrared or other wavelengths of electromagnetic waves to illuminate the surrounding scenery. This "active lighting" method allows night vision goggles to obtain clear images. However, it also makes it easier to expose the user's position.
(2) Passive night vision goggles rely only on residual light in the environment and do not emit any light. It has stronger concealment, but the imaging effect is slightly worse than that of active night vision goggles.
Each type of night vision goggles has its own advantages and disadvantages, and users can choose according to their actual needs. After choosing a suitable night vision device, you should use it properly and perform regular maintenance to maximize its effectiveness.
So how should you use the night vision device correctly?
(1) Adjust the focal length to make the image clear: Before using the night vision device, adjust the lens focal length to make the image as clear as possible.
(2) Keep the lens clean: Be careful not to leave fingerprints or other stains on the lens during use to avoid affecting the image quality.
(3) Open the cover to use: When using during the day, open the cover to block light to prevent strong light from damaging the night vision device.
(4) Waterproof and shockproof: Choose a waterproof and shockproof model based on product performance, which is safer to use in the wild.
Pay special attention to the correct use of batteries
(1) Choose the appropriate battery specification model: Use the battery model recommended in the manual strictly.
(2) Pay attention to the power at all times: Monitor the power during use to avoid damage after the power is exhausted.
(3) Replace the battery in time: Replace the battery immediately when the battery power is too low to avoid affecting the use.
Daily care and maintenance
(1) Keep the surface clean: Wipe the surface of the body with a special cloth regularly, clean the lens and display.
(2) Check the seal: Check the protection and seal regularly to ensure the waterproof and dustproof effect.
(3) Calibrate regularly: Calibrate the alignment and image quality according to the recommended period in the manual.
(4) Store properly: Store in a special box or bag in a cool and dry place.
Service life: There are many factors that affect the service life of night vision devices. Generally, it is recommended to conduct a comprehensive inspection after 10,000 hours of work to confirm whether it needs to be replaced.
FAQ
What other questions do you have about the use of night vision devices? Here are some of the most common questions:
1. Will long-term use of night vision devices hurt your eyes?
No. Night vision devices use a low-brightness green screen to display content, which does not pose a risk of radiation damage to the eyes and can be used safely for a long time. However, you still need to pay attention to eye fatigue.
2. Why do blurred images often appear during use?
If the image is still blurred after adjusting to the optimal focal length, it is likely caused by contamination on the lens surface. You can use a special lens cleaning cloth to gently wipe the surface of the lens. After removing the dirt, the image can be restored to clarity.
3. What are the differences in the field of view of different models of night vision devices?
The field of view ranges from tens of meters to hundreds of meters, which mainly depends on the design of the lens. The higher the end of the night vision telescope, the wider the field of view.
4. Why are the prices of different models of night vision devices so different?
The main reasons for the price difference due to different models include detection distance, image clarity and resolution, photomultiplier tube generation, etc. These factors directly affect the observation effect and performance.
5. Can night vision devices be used during the day?
Yes, but it is not recommended to use it for a long time in a strong light environment. The ambient light during the day is too strong, and the magnification function of the night vision device will cause glare and blur.
I hope the above answers can solve all your questions about night vision devices, and choose and use night vision devices more easily.
