anti dazzle mirror working principle

all actions of people are controlled by the brain nerve center, and the action instructions given by the brain nerve to various organs (such as hands and feet) are received by the brain nerve to various signals, the response after making a judgment. Specifically, human perception organs: eyes, ears, nose, tongue and skin feel external information, such as light, sound, taste and electricity, which are transmitted to the brain through the nervous system, after the brain makes a judgment, give instructions and take corresponding actions. For example, when your eyes see a red light on, your brain gives instructions --- pine door --- step on clutch --- shift --- step on brake --- stop. This is a normal reaction process. If the external information is too strong and exceeds the bearing limit of the sensory organ, the organ will be damaged and will stop working. For example, a strong light (such as laser) can blind human eyes, even lose your life. If someone suddenly shines a flashlight on your eyes at night, you will be shocked. Your eyes are white, at a loss, and you can't see anything. As you can know from the above examples, people's eyes have a certain visual range. Beyond this range, they will hurt your eyes, your visual cells, visual nerves, and even the nerve center. Similarly, when the other party comes to the car at night, the strong light of the high beam will hurt your visual cells and central nerves, It makes you feel at a loss, and the reaction is inappropriate. You don't know where to drive the car. In this way, traffic accidents will easily occur, causing a tragedy of the car is destroyed and the man is dead. The fundamental reason for the glare of car headlights is that there are too many ultraviolet light and high energy photons in the other car headlights, so as long as the ultraviolet light and high energy photons in the other car headlights are eliminated, no matter how big the power of the other headlight is, it will not be dazzling, just like a burning stove, because the light emitted by the stove is almost free of ultraviolet light and high-energy photons. Can sunglasses and sunglasses be used to block the strong light of the car lights? Although sunglasses and sunglasses can weaken the strong light of each other's headlights, the light of roads, pedestrians and obstacles in front of them is also weakened, and the road conditions cannot be seen clearly, so it should not only weaken the strong light of each other, to eliminate the harmful spectrum, it is necessary to enhance the useful spectrum, so that the other side's headlights are not dazzling, and the road and pedestrian obstacles in front of them can be seen clearly. This is the scientific anti-glare method and way out. Anti-glare mirror ---- using methods such as spectrum and wavelength principle analysis, using binocular imaging synthesis features of human eyes, the colored transparent polyacrylic acid methyl ester material which can reduce and block high-energy ultraviolet light is selected for injection molding into orange color filter plate, use the scientific ratio of orange color color masterbatch and other additives to PMMA or PC base materials, and then add a proper amount of brightener to keep the central wavelength of orange color light wave within the visual range of 500-680 nanometer human eyes, this kind of filter plate can filter out the high-energy ultraviolet light, partial purple light and blue light emitted by automobile headlights with short wavelength, highlighting 585 nanometer yellow light, the yellow light of this wavelength cannot block the long red light and green light, which makes the car light we see through the night vision mirror panel seem to have changed its color and become a soft yellow light, however, the light (brightness) of road conditions has not decreased, The reason why the traffic lights at the intersection can be seen clearly is that experts in visual physiology at home and abroad have long demonstrated that yellow is the most sensitive color to human eyes and the most acceptable color, it is the color that looks the most energy-saving and soft, and the color that is the least prone to fatigue;
