[LaOlivia]

Small black dots serve purposes such as sunshading, protecting the front windshield, and beautifying the edges of car glass. Below is an introduction to the functions of these small black dots on cars: 1. Protecting visibility: They help reduce glare from sunlight, allowing drivers 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 protect the windshield by reducing the intensity of direct sunlight exposure. 3. Decorating the car: The small black dots also serve an aesthetic function, making the edges of the car glass look more appealing and less monotonous.
