How to Use a Manual Anti-Glare Rearview Mirror?

Manual anti-glare rearview mirror usage: When the vehicle is exposed to strong light from behind, the manual anti-glare rearview mirror requires the driver to manually activate the anti-glare function to block the intense light from affecting the driver's vision. When not needed, the driver can manually deactivate the anti-glare function to clearly observe the traffic conditions behind. The anti-glare rearview mirror consists of a special mirror, two photodiodes, and an electronic controller. The two photodiodes are positioned on the front and back of the rearview mirror, respectively receiving light from the front and rear of the vehicle. When the headlights of a following vehicle shine on the rearview mirror, the light from behind becomes stronger than that from the front. This contrast is detected by the two photodiodes, which send an electrical signal to the electronic controller, applying voltage to the conductive layer of the mirror. This causes the electrochromic layer of the mirror to darken, ensuring that even the strongest light reflected on the mirror does not reach the driver's eyes.
I often encounter the problem of overly bright headlights from the car behind while driving, and that's when the manual anti-glare rearview mirror comes in handy. The usage is actually quite simple: just locate a small lever or button at the bottom of the rearview mirror and gently push it downward. Once pushed, the mirror will tilt slightly, softening the reflected light and eliminating the glare. When driving at night, if I see strong lights approaching from behind, I immediately push the lever, and the effect is instant. This feature is incredibly practical, helping to avoid eye strain and distraction, especially on highways or during long drives. For safety, I recommend regularly checking if the rearview mirror moves smoothly to prevent it from getting stuck. Once you get into the habit, driving becomes more comfortable, particularly during nighttime city driving when the lights can be chaotic—this tool is a lifesaver. In short, just push the lever, and it's done—don’t let it go unused.
