The Function of Double Curvature Mirror Glass
2023-11-04
A car's rearview mirror is the driver's second pair of "eyes" for the car owner. Because the main function of the rearview mirror is to expand the driver's field of vision and minimize the driver's blind spots, thereby improving the safety of the car and the driver. Drivers use rearview mirrors when changing lanes, turning, or getting out of the car, so the clarity and range of the rearview mirror are very important.
1. What is a double-curvature rearview mirror?
There are roughly two types of rearview mirrors, one is a smooth rearview mirror, and the other is a double-curvature rearview mirror. This kind of rearview mirror has a dotted line at 1/3 of the mirror surface. The outward part of the dotted line is the outside of the rearview mirror. The outside mirror is a convex mirror. Since the curvature radius of the convex mirror is small, the outside convex mirror will make the driver's field of view wider and farther. This double-curvature rearview mirror will play a greater role when driving at high speeds and turning, so that the driver can see the situation clearly in advance and take appropriate measures. Of course, not all cars have this kind of rearview mirror, so some car owners will install a small disc to assist vision.

2. Turning skills of double curvature rearview mirror
Some novice drivers cannot predict the distance between their car and the car behind them when turning, so they hesitate whether to turn. In fact, as long as the car behind stops inside the dotted line and does not continue to follow the car, and the surrounding conditions permit, car owners can make bold turns. In addition, we can prepare a bottle of rain repellent when driving on rainy days, so that we are not afraid of rain blurring our vision.
3. Advantages of double-curvature rearview mirror
In fact, the application of double-curvature rearview mirrors not only broadens the field of view, but also greatly reduces the size of the rearview mirror. The smaller size of the rearview mirror can not only reduce wind resistance and control noise, but also reduce the car's Fuel consumption. Originally, this kind of rearview mirror could only be seen on high-end cars. Now, with the continuous reduction of costs, many lower-priced cars have double-curvature rearview mirrors.
The outer side of the double-curvature rearview mirror accounts for 1/3 of the entire mirror surface and is a convex mirror, while the inner side accounts for 2/3 of the entire mirror surface and is a flat mirror. This design can double the driver's field of vision and eliminate blind spots when turning. In addition, car owners can prepare a rearview mirror rainproof film, so they don’t have to worry about rain in summer. They can also install rearview mirror rain eyebrows, which can effectively block rainwater.
Today, due to the increasing use of double-curvature rearview mirrors in the cars, the driver's safety has been increased.
