5 Ways To Take Care Of Your NVD

Night vision devices can run from a few hundred dollars to a few thousand depending on generation and technical capabilities so if you’ve bought one or plan on doing so, you’ll want to take full advantage of it for as long as possible.

1. Bright Lights

The number one night vision device killer is bright light. While most tactical shoppers know not to use their goggles or binoculars during the day, not everyone knows that sunlight is not the only danger to your gear. Flashlights, car headlights and any other source of bright light can seriously damage NVDs.

High-quality optical devices feature automatic turn-off overload circuits or offer separate light sensing mechanisms to protect your device against such damage. Even with these features, you shouldn’t expose your NVD to bright sources of light.

2. Impact

While sturdy and build using high-quality resistant material, night vision devices house delicate image intensifier tubes and, like any precision device, are susceptible to impact damage so handle them with care.

3. Exposure to fog and humidity

Electronic devices are not great friends with humidity or fog and neither are NVDs. High-quality devices can usually tolerate moderate exposure to humidity or damp environments but but prolonged exposure can seriously damage your equipment.


You can always opt for waterproof devices, such as the The Armasight Eagle, a regular work-horse that is not only able to satisfy the most demanding professional but is also extremely sturdy.

4. Abrasives

Do you use abrasive cloths or detergents to clean your eyewear? Then why use them on delicate lenses than can get scratched just as easily. Treat your NVD with the same care as you would a camera and clean your lense using special  tissues, like the ones designed for cameras.

5. Remove the batteries

If you don’t plan on using your night vision device for a while, remove its batteries before storing it in a cool, dry place. This way you avoid any battery leakage and, in the event of one, prevent damage to your device’s internal mechanisms.

Also, accidentally leaving your device on can decrease tube life and, since the coating on the image intensifier tube is based on tech similar to photographic paper, it can burn an image on the device’s visual field.

It’s highly recommended that you store your device in a cool, dry place since high temperatures and increased humidity can damage your gear.
