[. . . ] Bright light sources such as headlights may cause visibility to degrade or disappear completely. Conditions such as fog or extremely dark environments will decrease visibility. It may also flash during the first few seconds of use in dark environments. HOW NIGHT VISION WORKS Bushnell Night Vision products collect and amplify existing light through the objective lens, which is then focused on the image intensifier. Inside the intensifier, a photocathode is "excited" by the light and converts the photon energy into electrons. These electrons accelerate across an electrostatic field inside the intensifier and strike a phosphor screen (like a green monochrome TV screen) which emits an image that you can see. It is the acceleration of electrons, which provides gain and enhances the image.
