Why Does My Night Vision Monocular Shock Me When I Push the Power Button? – All You Need to Know!

If your night vision monoculars shock you when you push the power button then you need to fix it or do something about it.

Let’s see what we can do with such monoculars.

Why Does My Night Vision Monocular Shock Me When I Push the Power Button?

The most common reason for this is that there is a problem in the battery compartment of the monocular.

The batteries are usually located on the bottom of the monocular and if they have been damaged, they will leak acid into the interior of the monocular.

This acid will cause corrosion inside the monocular and eventually destroy the internal components.

If you have a night vision monocular that shocks you when you press the power button, you should immediately take it to an authorized repair center. They will be able to determine whether the problem is caused by a bad battery or some other issue.

How Night Vision Works

The first thing you probably think of when you see the words night vision is a spy or action movie you’ve seen, in which someone straps on a pair of night-vision goggles to find someone else in a dark building on a moonless night.

You may have wondered whether these things really work. Do you know if they’re helpful for you to be able to sleep better at night? Yes!

Ways Night Vision Works

With the right night-vision equipment, people can be seen from up to 200 yards (180 meters) away on a moonlit, cloudless night! Two types of night vision exist thermal imaging and passive infrared.

Image Enhancement

It collects the tiny bits of light, including the low end of the infrared light spectrum that is invisible to our eyes, and then amplifies them so that they’re visible to us.

Thermal Imaging

This technology operates by capturing the upper portion of the infrared light spectrum, which is emitted as heat by objects instead of simply reflected as light.

Objects that are hotter than others (such as people) radiate more heat energy than objects that are colder (like trees).

Infrared Light

To understand night vision, it’s important to understand something about lights. The shorter the wavelength of a particular type of lighting, the brighter it appears.

Visible lights (blue) have the most energy, and infrared lights (infrared) have the least. Next to the visible spectrum is the invisible infrared spectrum.


Infrared light can usually be divided into three categories

Near-infrared (near-IR)

Closest to visible light, near-IR has wavelengths that range from 0.7 to 1.3 microns or 700 billionths to 1,300 billionths of a meter.

Thermal-infrared (thermal-IR)

Occupying the largest part of the infrared spectrum, thermal-IR has wavelengths ranging from 3 microns to over 30 microns.

Mid-infrared (mid-IR)

Mid-IR is in between the near-IR and thermal-IR regions, with wavelengths ranging from about 4 microns to 20 microns.

Our eyes cannot see mid-infrared (MIR) radiation because it’s too near visible wavelengths. But MIR radiation is absorbed by water in our bodies, making it useful for medical purposes.

Key Difference

The main differences between thermal-IR and visible light are that infrared light is not reflected but rather emits from objects, whereas visible light is reflected.


Night vision cameras are used for various purposes including

  • Advertisement
  • Military
  • Law enforcement
  • Hunting
  • Wildlife observation
  • Surveillance
  • Security
  • Navigation
  • Hidden-object detection
  • Entertainment


The original purpose of nighttime visibility was to help soldiers see their enemies during dark hours. However, it has since been adopted by civilian applications as well, including for use in vehicles, boats, aircraft, and even space exploration.

Police and Security

Police and security often use both thermal-imaging and image-enhancement technology, particularly for surveillance.


Hunters and nature lovers use NVGs to navigate through the woods at nighttime.


Detectives and private investigators use night vision to watch people they are assigned to track.


Many companies have permanently mounted security camera systems that are equipped with night vision capabilities.

Thermal Imaging Applications

A really amazing ability of thermal imaging is that it reveals whether an area has been disturbed — it can show that the ground has been dug up to bury something, even if there is no obvious sign to the naked eye.

Police use thermal imaging cameras to detect objects that have been concealed by criminals, including money and drug caches.

Recent changes to areas such as wall surfaces can be detected by thermal imaging, which has helped solve some crimes.

Night Vision Monoculars

A monocular is a device used by people who want to be able to look through binoculars without having to hold them. It has an illuminated target and a built-in IR illuminator, allowing you to view things even when there isn’t enough light available.

Field of View (FOV)

With its wide FOV, the Night Vision Monocular allows you to see clearly whatever is right in front of you while still seeing everything else at a distance.

IR Illuminator

It has an integrated infrared illuminator, which allows you to view things even when it’s completely dark out.


This monocular has a built-in carry bag, so you can take this monocular wherever you go. It can be attached to any tripod or monopod.

This monocular is perfect for hunting, hiking, campi­ng, fishing, and more!

Frequently Asked Questions (FAQs)

Do Night Vision Goggles Work in Total Darkness?

Thermal imaging cameras work on thermal radiation (heat) and can be used effectively even in complete darkness because they detect the heat radiated from objects around the camera.

Can You Get a Night Vision Camera on Your Phone?

There is an app called “Nigh Vision Camera” which can significantly improve the quality of photos taken at nighttime from your smartphone.

How Far Can Night Vision Binoculars See?

When choosing binocular lenses, be sure to take into account their viewing distance. Binocular lenses usually offer a maximum viewing distance of up to 800 feet.

Are Night Vision Goggles Legal in Canada?

All gen 1 and 2 military-grade binoculars, monoculars, riflescopes, and thermal imaging devices are legal in Canada.

How Good Is Human Night Vision?

We, humans, are nocturnal creatures. So our eyesight is best when we sleep. Nocturnal animals’ eyesight is better than ours at night.


Many people are discovering the unique world that can exist after dark has fallen.

If you’re out campi­ng or hunting a whole bunch, there’s a good chance that night-viewing equipment can be useful to you — just be sure to buy the right kind for your needs.
