Does Car Glass Have a Speed-Reducing Visual Effect?

[SanCarlos]

Car glass does have a speed-reducing visual effect. Here are the relevant details: 1. Speed-reducing glass: Speed-reducing glass is essentially the laminated front windshield commonly referred to in cars. Some tempered front windshields have poor optical performance and uneven transitions, which can cause drivers to experience eye fatigue and dizziness after prolonged driving. In contrast, glass with good optical performance and no optical distortion provides clear visibility from inside the car. Additionally, the incorporation of new technologies makes the light passing through the glass softer, thereby creating a sensation of reduced speed. 2. Principle: The principle of glass is to transmit light, and the best effect it can achieve is to make the presence of the glass indistinguishable from its absence. In reality, speed-reducing glass does not make the movement of external objects appear slower than their actual speed; instead, it makes them appear consistent with the actual speed—just as if there were no glass at all.
