What to Do When the Outside of the Windshield Is Blurry?

[VanVanessa]

Open all the car windows. When the air inside the car circulates with the outside air, the fog on the car's front windshield can quickly disappear. Below is relevant information about the car's front windshield: 1. The windshield has curvature: Car windshields have curved deformations at the edges where they contact the car body. This curvature causes external scenery to distort when viewed through it, affecting the visual perception of passengers inside the car and creating a deceleration effect. It's similar to looking at a newspaper through a magnifying glass—the scenery in the middle appears to move slowly, while the scenery at the edges appears to move quickly. Additionally, the edges of the windshield have fading dotted black decorative borders, which also contribute to this effect. 2. Function of the curvature: While driving, the curvature of the windshield causes the movement of reference objects on both sides of the car to gradually slow down, creating the perception that the front windshield has a deceleration effect. This shares some similarities with a magnifying glass.
