Why are the two mirrors of a car not the same size?

Since the driver is sitting on the left side of the car, the rearview mirror on the left and right sides will be different from the driver's line of sight. In order to restore the actual scene as much as possible, so that the driver's rearview mirror is the same as the left and right scenes, the rearview mirror of the car is designed to be inconsistent on the left and right. With the driver's seat on the left, the left side mirror will be relatively large, while the right side mirror will be smaller, and vice versa.

The rearview mirror is not a flat mirror, but a convex mirror. Convex mirrors have curvature (the degree to which the mirror is curved). The image it reflects is smaller than that of the eye, but the field of view is large, which is equivalent to the "wide angle" of the camera.

The greater the curvature, the wider the range, but the greater the distortion. The mirror on the driver's side is large and has little curvature; The other side has a small mirror surface and a large curvature. In this way, the driver's left and right vision can be basically the same.

The role of the rearview mirror for driving safety should not be underestimated, and it can be said that the rearview mirror is the driver's "third eye". So how should the rearview mirror be adjusted? The first thing to understand is that everyone's height, sitting posture, etc. will have a great impact on the driving vision, so the premise of adjusting the rearview mirror is to not affect the driving, adjust a sitting posture that suits you, and then adjust the left and right rearview mirrors.

The left side of the line of sight is better, the blind angle of the rearview mirror is small, the observation range that can be adjusted is larger, and the horizon line is placed in the middle of the rearview mirror. It is best to take care of the rear of the car, and it is more convenient to drive and reverse. Therefore, it is necessary to adjust the reflection of the horizon in the distant part of the rearview mirror to the mirror**, and adjust the reflection of the left body to occupy the area of 1 4 on the right side of the mirror.

The dead angle on the right side of the body is larger, the distance of the rearview mirror is smaller, and it can be appropriately lowered than the left side, the horizon is above the middle of the rearview mirror, and the ground observation range accounts for about 2 3, and the image of the right side of the body is adjusted to occupy the area of 1 4 on the left side of the mirror.

**Rearview mirrors.

From the driver's seat, the entire rear window is in the mirror**, and the distant horizon is just in the middle of the mirror.

Generally, the left side mirror will be relatively larger. Because the rearview mirrors are convex mirrors, the mirror on the driver's side is large and the curvature is small, while the mirror on the other side is small but the curvature is large, so that the driver's left and right sides of the vision can be basically consistent.

The rearview mirror is not a flat mirror, but a convex mirror. Convex mirrors have curvature (the degree to which the mirror is curved). The image it reflects is smaller than that of the eye, but the field of view is large, which is equivalent to the "wide angle" of the camera.

Let the driver see the rearview mirror on the left and right, and the rearview mirror of the car is designed to be inconsistent on the left and right. The driver's seat is on the left.

Both side mirrors of the car are the same size.

This is to allow the driver to see the scenery on both sides more clearly.

This is presumably determined by the position of the driver.

The mirrors on both sides should be the same size, right?

That's impossible, it's all going to be the same big.

Aren't they all the same size under normal circumstances?

: As a left-hand drive car, the left side mirror is relatively larger. Because the mirrors of the exterior mirrors are convex mirrors, the mirror surface on the driver's side is large and the curvature is small, while the mirror surface on the other side is small, but the curvature is large, so that the driver's left and right sides of the vision can be basically consistent, so that it is more convenient to observe the situation behind the car when driving.

Because the driver's line of sight will be different when looking at the rearview mirrors on the left and right, it is necessary to restore the original situation, so the rearview mirror can only be changed.

Because the driver sits on the left side of the unknown, far from the right side mirror, it is larger.

The angle of view is different, in order to restore the scene, and change the rearview mirror.

Looking at the left and right mirrors from the driver's seat, there is a difference in itself.

This may be the reason for the manufacturer, so that it is convenient for the driver to use.

It is formulated according to the distance from the driver, in order to better use.

This is set for the convenience of the driver to observe the back.

It is convenient for the driver to observe the back of the car.

Tell you a method, experience it yourself and you'll understand it immediately.

1. You sit down! The effect is more pronounced when the environment is smaller.

2. Look back to the left, reach the limit, and remember what is in your field of vision; Look back to the left again, reach the limit, and remember what you are looking for. Turn your head back to the positive position.

3. Move one meter parallel to the left, keep other postures unchanged, still sitting, repeat the above actions, you should find a change in your career.

That's how the left and right mirrors are different, and if you add that you can sit in a car**, it's like driving a motorcycle or a Formula 1 car, and it should be the same.

The Yihe double curvature blue mirror I changed also works very well! Hehe.

Because you're close to the left mirror, far away from the right mirror.

The difference in the distance shown by the exterior mirror and the interior mirror is due to the need for vision, so the curvature of the mirror is different, resulting in the different distances seen by our eyes.

The function of the exterior mirror is to observe the view of the rear side of the car, so as to make a pre-judgment when changing lanes or making a U-turn, so the field of vision should be as wide as possibleThe rearview mirror in the car is to observe whether there is a car directly behind the car, which is more positive at all angles, and you can know at a glance, and you don't need a large field of vision.

Generally speaking, in my experience, I first look at the exterior mirror to determine whether there is a car, and then look at the interior mirror to determine "how far away". In this way, you can accurately judge when changing lanes. Sometimes you can see the car farther away in the exterior mirror, but it is actually closer to you, and if you change lanes rashly, it will cause an accident, so it is best to take another look at the interior mirror to see the actual distance before making plans.

Every part of the car has a purpose, and it's done for safety reasons, and it's not a strange design.

The curvature of the interior mirror and the exterior mirror are different. The rearview mirror of the car is actually not the flat mirror that we usually use at home, but a haha mirror with a curvature. Because of the curvature, the car rearview mirror has a larger viewing angle, otherwise we can only see a small part of things through the rearview mirror, including the car behind and pedestrians, which may cause danger.

Some drivers will also put a small mirror with a larger arc on the exterior mirror, so that they can see the wheels.

In order to expand the angle of the exterior mirror, it is convenient to observe the vehicle behind it, so the viewing angle is larger, and the result is that the things in the mirror seem smaller, and people's subconscious is near and far away, so it feels like it is farther away than it actually is. The interior rearview mirror does not need to have such a large viewing distance, as long as you can see the situation at the rear of the car, so the arc is smaller than the exterior mirror, and the viewing angle is smaller, so that it seems that the car and people behind are closer to us.
