Auto plastic parts - how to choose rearview mirror?

Car rearview mirror is the main safety equipment to ensure safe driving, but at present, the rearview mirror installed on various cars, whether it is a flat mirror or a spherical convex mirror, has blind spots to varying degrees, and the width of the field of view is insufficient, and the driver is turning and changing. When driving, overtaking or being overtaken, you often have to lean forward or turn your head left and right to find the obstacle. Therefore, there are always hidden dangers that affect the driving safety. So how to choose car rearview mirror?
1. Determine the electric heating device
If the rearview mirror of the vehicle is not equipped with an electric heating device, you can choose a multi-curvature large-view rearview mirror, a stick-type spherical mirror or a double-curvature large-view rearview mirror. If there is an electric heating device, you can choose a multi-curvature large-view rearview mirror and a double-curvature large-view rearview mirror.
2. Determine the structure
The first-generation vehicle rearview mirror products are stick-on spherical mirrors and single-curvature spherical mirrors. The shortcomings are that they are outdated and have many shortcomings. The second generation is a double-curvature rearview mirror with a large field of view. Some of the original cars are equipped with this kind of product, but the scenery is deformed and stretched greatly.
There is also a multi-curvature rearview mirror with a large field of view, which has a large field of view, small distortion, and no deformation or stretching of the scene.
