How to care for your night vision equipment

In this article, we will talk about how to take care of your night vision equipment. But, first, let us answer this relevant question; “how does night vision work”. The answer is that it depends on the tools you are using. There are two kinds of technology applied in night vision equipment. They are thermal imaging and image enhancement. As the name implies, thermal imaging technology involves heat while image enhancement brightens the existing light. Now, let us discuss the main reason for this article. It is important to maintain your Night Vision Equipment as it will deliver optimal results. If you own any of these tools; a night vision scope, a thermal scope, or a set of night vision goggles, then you are sure of two things:

  • These devices are very expensive
  • Your night vision tool gives you an undue advantage for security, hunting, etc.

To enjoy these devices, you need to protect and care for them when they are not in use.

Here are some guidelines you can follow to maintain optimal performance thereby prolonging the lifespan of your night vision equipment.

Adhere to Instructions

The parts that make up these night vision devices are very fragile. Even a little scratch can render the devices useless. Besides damaging the equipment, it may jeopardize the lives of the user as well as others present in the area if you are using thermal riflescopes or night vision scopes. To avoid such kind of mistakes, it is vital to follow the instructions as illustrated in the operator manual.

Humidity and Fog

Rain will damage devices, but, hope you are aware that high humidity and fog can damage some devices too. As applicable to the majority of electronic devices, night vision devices are vulnerable to water thereby requiring some level of protection. Some night vision equipment is particularly susceptible to fog.

Wet Batteries

You don’t consider this but replacing batteries in a wet environment can weaken the weather-proof layer on many regular devices. Some devices only come with seals for the battery compartment and that is the only protection for it. Ensure that your batteries are kept in a weatherproof case as it will protect your battery when you go to replace them.


Night vision devices are essentially made for night purposes, so their construction is typically robust. However, this does not validate you to beat them up. Sensitive parts have to be protected by using materials that soak up the impact of the equipment falls. Always use mounts, hand straps, and handles appropriately and mount them on areas that are set up for it, like helmet mounts or weaver rails.

Bright Light

Most of the lower part of the night vision equipment is damaged by bright light. That is the reason many practical users will not put on their goggles during the day time. Some even say that you should always protect your equipment from sunlight exposure. Light can damage devices depending on their intensity, source, and level of exposure.

Cleaning your devices

Always follow instructions on the manual when cleaning your equipment as the majority of these devices get damaged during the cleaning process. It is unwise to use the abrasives and detergents as this is highly discouraged. You can use a damp rag to clean the outer part of the devices.


If you don’t plan to use the devices for some time, it is better to eject the battery. Store these devices in the condition as stated in the user manual. Switch off the device or close the aperture whenever you are not using it to increase the lifespan of your tube.
