What Causes Light Scattering When Viewed Through the Windshield?
2 Answers
The phenomenon of light scattering when viewed through the windshield may be due to the absence of an automotive glass film or the use of a low-quality film. Reapplying a new film can resolve this issue. Below is additional information: 1. Windshield: Currently, most automotive windshields are made of laminated tempered glass or zoned tempered glass, which can withstand strong impacts. Zoned tempered glass is a new variant of tempered glass that undergoes special treatment to maintain some clarity in the event of impact-induced cracking, ensuring the driver's field of vision remains unobstructed. 2. Precautions: When driving at high speeds, the windshield is highly susceptible to being hit by flying small stones, which can cause minor cracks or dents at best, or shatter the glass at worst. If the windshield is shattered, it should be replaced promptly.
I've been driving for over ten years, and the issue of light dispersion on the windshield is quite common. The main reason is dirt on the glass surface, such as oil film buildup or dust, which causes light to scatter. It's more noticeable during rainy or foggy weather because water droplets amplify the dispersion effect. Regular cleaning is essential—use a dedicated glass cleaner and avoid ordinary cloths, as they can make the problem worse. This issue is particularly dangerous at night when it's hard to see oncoming headlights, increasing the risk of accidents. I recommend checking the windshield weekly to develop good habits—safety first.
