Also known as a rear-view mirror, the convex mirror in a car has a significant role. Such mirrors function whenever a wider field of view is necessary, making the driver aware of their surroundings. You can easily see what's happening around and behind you, which ensures your safety and that of others on the road. Therefore, driving without rear-view mirrors is risky and can cause accidents. 

Remember that the mirrors used in cars differ from those at home. A convex mirror has a broader field of view than a plane mirror, which is why they are used as rear-view mirrors in cars.

This article explains more about convex mirrors and how they work as rear-view mirrors in vehicles.

What are Convex Mirrors?

Convex mirrors are curved with a reflective surface protruding towards the light source. This is different from the concave mirrors, which curve inwards. Since they can reflect the light source outward, they can't work to focus light. This is why vehicles use convex mirrors as rear-view mirrors.

The bulging of the convex reflective surface toward the light source enables the mirror to capture more from the surroundings than a concave or flat mirror. Convex mirrors provide a wider field of view, making them appropriate for specific applications of rear-view mirrors in cars.

Usually, convex mirrors portray images of objects as smaller than they are in reality. However, as the object approaches the mirror, it becomes more sizable.

How Does a Convex Mirror Work?

  • Convex rear-view mirrors let you see a wide area of the surroundings without moving your head or repeatedly adjusting the mirror.
  • The convex mirror has a small inscription beneath. Hence, objects that pop in the mirror tend to be closer than they are in reality. The mirrors with convex surfaces curve outward towards light sources, offering a virtual view of the object.
  • The virtual image tends to appear smaller than the real object. As a result, the mirror enables you to see more of your surroundings due to the virtual image it creates.

How To Use Convex Mirrors in Cars Properly

To use a convex rear-view mirror in the car properly, follow these simple tips:

  • Position the mirror right to offer the utmost viewing angle, providing a broader and clearer view of the surroundings. Ensure you change the mirrors before you start driving to position them correctly. A more precise view will enhance your driving.
  • Adjust the mirror appropriately, depending on your height and seating posture, to offer the best viewing angle.
  • You can use the convex mirror together with the flat mirror. Even though a convex mirror offers a broader field of vision, a flat mirror is still essential to help reflect the speed and distance of the vehicles behind you.

Advantages of Convex Rear View Mirror

Convex mirrors in vehicles offer advantages like the following:

  • Reduces Blind Spots: Using convex mirrors may help reduce blind spots, which are areas on the road that are difficult to see. The mirror's wider curvature increases the viewing angle.
  • Offers a Wider Angle of View: Convex mirrors offer more extensive visibility in the surrounding areas because of their design. The comprehensive view makes it easier for the driver to decide when to change lanes or exit a road. Furthermore, the driver can easily track what's happening behind the car.
  • Improved Safety: Convex mirrors offer a wider view of the surroundings, helping the driver stay more aware of the areas within. This reduces the chances of accidents.

Disadvantages of Convex Rear View Mirror

Even though convex mirrors aid rear-view mirrors in cars, they still have some cons, like:

  • Sometimes, the convex mirror can make it difficult for the driver to judge the vehicle’s speed coming from behind.
  • Due to their inbuilt nature, convex mirrors tend to distort the reflections. They can offer altered or false images reflected by the mirror.
  • The convex rear view mirrors can make it challenging to view distant objects or vehicles and to judge their distances.

Conclusion

Convex mirrors in vehicles are essential for safety enhancement. They offer a larger view of the areas within, keeping drivers more aware of their surroundings. Alongside the mirrors, you also need a good car insurance policy to benefit from wide-ranging coverage for the insured vehicle. In case of damages to your car due to an unexpected accident or natural or manmade calamities, you can benefit from the insurance coverage.
