If it works, an infrared night vision device will throw glasses infrared light onto a surface. Infrared light is invisible to humans, but a special camera (lenses) in the infrared night vision goggles can see the objects in the infrared range. The camera allows light and objects, then transfers the image to the user, so the wearer can see objects through infrared night-vision goggles.
This type of active infrared night vision goggles have been introduced and used during the Second World War by sharpshooters looking for some targets at night. But as this type of infrared night vision goggles is active to emit infrared light on the search area, but the light can not be seen by humans but can easily be recognized by those who hate wearing glasses even . In fact, infrared goggles are not weapons grade, not more. But the infrared night vision goggles are still widely used for the safety of property and other civilian uses.
