Difference Between Driving Glasses And Night Vision Goggles
Polarized glasses are made according to the principle of the polarization of light. Night vision goggles are an auxiliary observation tool based on night vision technology with the help of photoelectric imagers. Driving glasses are made according to the lens polarized angle and radian, on the basis of the principle of precision optical design. They can only make good light pass through, and other light sources, like the strong sunlight, the glare of a light source like a car headlight is filtered, thus removing the interference of external light, to avoid the presbyopia, dazzling, and so on. Night-vision goggles are divided into two kinds: One is Night Goggles, and the other one is Thermal Goggles. Image intensifying night vision technology is a photoelectric imaging technology that enhances the faint target image illuminated by night skylight through night-vision goggles with an intensifier tube for observation.
