Night vision is used widely in home security. There are two ways to achieve night vision technologically-through an enhanced spectral range and enhanced intensity range.
Night vision through enhanced intensity range uses an image intensifier to enhance the available light. It uses a photocathode plate that acts in the same way as a cathode ray television, creating an "intensified" image on an image screen, similar to a television screen. The resulting night vision image is brighter than the available light, enabling a user to see in the dark.
Night vision that uses enhanced spectral range allows the viewer to see bands of the electromagnetic spectrum that are otherwise unavailable. This allows the viewer's eyes to see infrared and ultraviolet radiation.
Night vision glasses, such as telescopes, use large lenses to gather light and project it into the eye of the user. However, most users cannot fully take advantage of this, as the human pupil has a limited amount of dilation. Before the advent of night vision goggles, soldiers were issued atropine, an substance that would force pupils to dilate.
Night vision goggles use image intensifiers over each eye. This gives the night vision goggles an advantage over monocular types of night vision due to the increased depth perception.
