The mirror in the middle of the car is called the rearview mirror, primarily designed to allow the driver to observe the situation behind the vehicle without changing their field of vision. Depending on the material, rearview mirrors can be categorized into aluminum mirrors, chrome mirrors, silver mirrors, and blue mirrors. Based on the shape of the mirror surface, they can be divided into flat mirrors, spherical mirrors, and dual-curvature mirrors. According to their functionality, they can be classified into auto-dimming rearview mirrors and manual-dimming rearview mirrors. An auto-dimming rearview mirror consists of a mirror, two photodiodes, and an electronic controller. When the sensor detects that the light on the mirror is too bright, it darkens the mirror glass, thereby reducing the light refraction and effectively protecting the driver's eyes. A manual-dimming rearview mirror typically consists of two lenses with different refractive indices, allowing the driver to switch between them using a lever to reduce the reflection of light.
