The anti-glare rear-view mirror is usually placed in the compartment. It is composed of a special mirror on the wall, two photodiodes, and an electronic controller. The electronic controller draws the front-light and back-light signals sent by the photodiode. If the light is illuminated on the rearview mirror of the car, the back light is greater than the front light, the electronic controller will output a voltage to the conductive layer, and the voltage on the conductive layer changes the color of the mirror electrified layer. The higher the voltage, the deeper the color of the electrified layer. No matter how strong the light shines on the rear-view mirror, the anti-glare rear-view mirror reflects the driver's eyes to show dark light. The reflected light from the specular electrochemical layer automatically changes continuously to guard against glare based on the incident intensity of the rear rays. When the vehicle is backing up, the anti-dazzle effect of the interior mirror is cleared, and the right exterior mirror automatically illuminates the ground. jinyulong now replaces silver mirrors and aluminum mirrors with chrome mirrors. Although the reflectivity of silver and aluminum is clear, there are side effects in places with high reflectivity. The blue mirror is a precision coating of titanium dioxide and silicon dioxide on a glass substrate. The precise instrument controls the thickness of each film layer through multi-layer electroplating. At night, when the headlights of the rear car illuminate the vehicle, or when the sun rises and falls in the daytime, the rear-view mirror reflection will cause the driver to have a dazzling sensation and affect the driving tranquility. Although the chrome mirror can probably handle the glare problem, but its reflectivity is low, and the vision on the small path at night will be dark, especially the dark solar film on the window, which looks more and more dim. Visible light with the usual high wavelength is easily bred to produce glare, and the blue mirror reflection can probably interfere with the interference of glare to produce and convert it into blue light. Blue light is probably the most compliant light for human eyes. Now blue mirrors are mostly used in European premium cars as rearview mirrors.
