Working
Let's understand the basic working of the kids' night vision goggles. Basically, there are two types of night vision goggles called the active and the passive night vision goggles. In the passive night vision goggles, only the available light is amplified and you can't see anything if there is total darkness. Active night vision goggles, on the other hand, project an infrared image through the goggles, that is, they have an inbuilt infrared 'illuminator' (backlight) that acts as a source of light even in the darkest conditions.

The night vision goggles work on the principle of photo electric effect which states that if a polished plate is exposed to electromagnetic radiations, it emits electrons (the electrons are called photoelectrons. Instead of going into too much details of photoelectric effect, let's understand how it is used in such googles. In the night vision goggles, the photoelectric effect is used to amplify the photons or packets of light energy. A lens system collects the light falling on it and sends it to a glass plate coated with photoelectric material on the back side of the goggles. By the use of another device, called the photo multiplier, thousands of electrons are ejected and all strike on a fluorescent screen that gives the eyes a visibility of the object.
