What are the small dots on the car windshield?

[ThomasFitz]

The small dots on the car windshield serve purposes such as sunshading, protecting the front windshield, and beautifying the edges of the car glass. Below are the functions of these small black dots: 1. Protecting visibility: They help reduce glare from sunlight, enabling the driver to maintain clear vision while driving. 2. Protecting the windshield: When sunlight directly hits the windshield, it causes thermal expansion and contraction. The small black dots help mitigate this effect by reducing the intensity of direct sunlight on the windshield. 3. Decorating the car: The small black dots also serve an aesthetic purpose, making the edges of the car glass look less plain and more visually appealing.
