How to Use a Manual Anti-Glare Rearview Mirror?

Manual anti-glare rearview mirror is used by: when the anti-glare lever under the rearview mirror is pushed forward, the entire mirror surface will tilt upward by about 10 degrees, at which point the manual anti-glare rearview mirror is activated. The mirror of a manual anti-glare rearview mirror is not a flat mirror with uniform thickness, but rather a wedge-shaped mirror with an angle of about 10 degrees. The anti-glare function of the manual anti-glare rearview mirror is actually achieved through the mirror's structure. The rearview mirror has two reflective surfaces with different reflectivity, installed at different angles. During the day, the high-reflectivity surface is used to ensure a clear reflection of the rear view. When exposed to strong light from behind, the lever activates the low-reflectivity surface, reducing the light intensity to avoid affecting the driver's vision. This is the principle behind its anti-glare function.
Having driven for decades, I'm quite adept at using manual anti-glare rearview mirrors. The small switch located below or on the side of the mirror requires just a gentle flick to adjust the mirror angle, effectively redirecting glaring headlights from vehicles behind and preventing visual fatigue during night driving. I recall one instance on the highway when intense headlights from behind were blinding—a simple switch adjustment instantly restored clear visibility. The operation is effortless, requiring just a finger movement without distracting from driving. I recommend cleaning the mirror surface and checking the switch during each car wash to prevent jamming or dust accumulation. Though small, this feature is crucial for safety—it significantly reduces the risk of fatigue caused by glare. If the mirror stops functioning properly, get it repaired immediately without delay. Developing this habit makes long-distance driving much more comfortable.
