What is the purpose of the small mirror inside the rearview mirror?

The functions of the small convex mirror on the rearview mirror: 1. Reduce blind spots: During daily driving, due to certain blind spots in the driver's line of sight, it is often difficult to notice some overtaking situations, which can lead to unnecessary accidents. Installing a small convex mirror on the rearview mirror can eliminate the blind spot on the right rear side of the vehicle. 2. Make reversing easier: Normally, drivers cannot see the sides of the car body or the rear wheels while driving. With the small convex mirror installed, it expands the driver's field of vision, making it easier to see the position of the rear wheels when reversing. For beginners, parking in reverse becomes much simpler.
I've been driving for over a decade and often encounter the problem of glaring lights when driving at high speeds at night. The small mirror inside the rearview mirror is designed to be anti-glare, mainly to reduce the strong reflection of headlights from vehicles behind, preventing them from directly shining into the eyes and affecting visibility. I remember one time on a suburban night road, an SUV was following closely behind me with its headlights on extremely bright, making the mirror a blurry white and hard to see the road. I flipped the small mirror lever, and the mirror automatically tilted and darkened, softening the light significantly while still allowing me to clearly see the outline and movement of the car behind. This feature is particularly practical—manual anti-glare requires your own adjustment, while automatic versions use built-in sensors to regulate light intensity. It not only enhances driving comfort but also helps prevent nighttime fatigue and accidents. I recommend that drivers familiarize themselves with this function and perform a simple test before driving to ensure it works properly, especially useful during long trips.
This small detail in safe driving is crucial. The small mirror on the rearview mirror is an anti-glare helper, allowing me to maintain clear vision at night or in tunnels. I used to think it was just a decoration, but after a close call—during a heavy rain at night, a truck behind me flashed high beams, turning the mirror completely white, nearly causing me to miss an exit and dangerously change lanes—I realized its importance. With this small mirror, the reflected light is weakened, allowing me to stay focused on the road ahead and the sides. The automatic version detects light intensity and darkens automatically, while the manual version requires flipping the mirror structure. It’s not just effective at night; it also helps in foggy conditions or when sunlight reflections are intense. Making it a habit to use it properly can significantly reduce distraction risks, ensuring safety for yourself and others. It’s best to clean that part regularly to prevent dust from obstructing the sensor’s function.
