Inside-rear view mirror (IRVM) helps drivers to see what’s behind the vehicle. They are of tremendous value when it comes to safety and watchful driving. An auto-dimming IRVM is a special type of mirror that has an element of an electronic system to detect lights. With the help of photo sensors, they automatically adjust incoming lights from cars behind to offer a non-glaring mirror view to drivers. Mounted on the car’s windshield, this device aids during low-light conditions or night driving.

How Does Auto-Dimming IRVM Work?

As a modern safety feature, it is recommended to buy a car that has an IRVM installed. If your vehicle does not have an in-built system, you can always purchase them from outside. The working mechanism of auto-dimming IRVM in a car is explained below:

  • Electrochromism

An auto-dimming IRVM is an electrochromic device that allows automatic adjustment of light reflections from other vehicles through a change in opacity. This happens because a gel-like material on the surface of the mirror glares differently upon being hit by an electric source.

  • Sensors

Special sensors mounted on these IRVMs immediately capture any change in the intensity of incoming light, enabling auto-dimming as and when required.

  • Light Detection

The detection of high-intensity light triggers a response from the control unit in the form of an auto-dimming activation that guides the premise of the device’s working.

  • Electrochromic Activation

The activated control unit darkens the mirror by sending an electric current to its coating, initiating a reverse reaction.

  • Auto Dimming

The gel helps direct the mirror to reflect less light, dimming the glare from car headlights behind.

  • Continuous Monitoring and Restoring Normalcy

Once the source light has sufficiently dimmed, the reversible process of colour change and brightening takes over to ensure that conditions are optimal for safe driving. This happens via adjustments in the electric current emitted by the sensors to trigger the mirror’s electrochromic layer so that the IRVM functions as any ordinary rear-view mirror.

Advantages of Auto-Dimming IRVM

With a primary aim to provide a safe driving experience during low-light conditions, let’s look at the benefits of using an auto-dimming IRVM in a car:

  • Reduced Glare

A prime feature of this IRVM is the automatic adjustment of reflections generated by the high-beam headlights of other vehicles. This protects the driver from the blinding effect of the light from behind.

  • Better Visibility

These IRVMs, because of their electrochromic ability, effectively manage light conditions to enhance on-road visibility.

  • Enhanced Safety

Better on-road visibility translates to greater road safety since drivers do not lose focus. Knowing that such a feature exists to prevent sudden changes in brightness also helps drivers concentrate more on their driving.

  • Safer Night Driving

Auto-dimming IRVMs are particularly helpful in controlling nighttime conditions.

  • Auto Transition

The reversible mechanism in auto-dimming IRVM facilitates conversion to normal mirror viewing during ideal driving conditions. This contributes to smooth experience with reduced risks.

Uses of Auto-dimming IRVM

These special mirrors have upgraded automobile driving to new standards of safety and comfort. Here’s a look at its uses:

  • Auto-dimming IRVM improves drivers' visibility by helping them react more swiftly to possible risks. It also helps them view and avoid blind spots, reducing the risk of accidents.
  • It effectively cuts off the glare from high-beam headlights and reduces eye strain, which can cause fatigue and discomfort while driving. It is useful during long-duration drives, which generally put more stress on the eyes.
  • Unlike ordinary rear-view mirrors, the automatic dimming feature means that IRVMs do not need to be continuously adjusted or flipped to reduce the glaring effect of bright lights.
  • Auto-dimming can also assist in vehicle parking by facilitating better assessment of the surrounding spaces from a distance.

Conclusion

The auto-dimming IRVM in cars is a wonderful technology of the modern automobile industry. Vehicles with this feature are labeled as ‘auto-dimming’, ‘electrochromic’, or EC for easy identification.
