Problems solved by technology

The current rearview mirror mainly uses a mirror with a high reflectivity of more than 90%. It is very advantageous to use it in the daytime or in an environment with high light intensity such as high beams. However, when there is strong light from the rear at night, The reflected strong light will strongly stimulate the human eyes, making it difficult for the driver's eyes to see the surrounding things clearly; currently, the driver puts away the rearview mirror when encountering such strong light; this kind of ordinary anti-glare rearview mirror is used The process is very troublesome and needs to be manually adjusted depending on the environment, and due to the poor reaction time of the human eye and brain, there is a great potential safety hazard; especially in summer and other seasons and areas with high sunlight intensity, strong sunlight and trailing cars The strong light of the high beam will cause the rearview mirror of the car to produce a dazzling rear view. When the light intensity reaches a certain intensity, the eyes of the person will be blinded instantly, and the brain will be dizzy, which will cause personal safety and road traffic. big security risk
