Is it necessary to apply film on car windows?

Applying film on car windows is not mandatory; it depends on personal preference. However, it is strictly prohibited to apply film on car headlights, as doing so can affect the lighting performance, especially with colored films. Car window film refers to a thin layer applied to the front and rear windshields, side windows, and sunroof, also known as solar film or heat-insulating film. Its primary functions include blocking ultraviolet rays, reducing heat, preventing injuries from shattered glass, minimizing glare, and, thanks to its one-way visibility feature, protecting personal privacy.
I live in a southern city where summers are extremely hot, and I feel that window tinting is almost a necessity. Without tinting, the sunlight directly shines in, making the steering wheel too hot to touch and the seats unbearably warm to sit on. After applying the tint, it's much better—it effectively blocks UV rays, preventing skin from getting sunburned, and also provides thermal insulation, allowing the air conditioning to be set lower for a cooler interior, saving a lot on fuel costs. More importantly, from a safety perspective: in case of an accident, the tint can prevent glass from shattering and flying, protecting passengers. Especially during long-distance driving, without tinting, fatigue sets in easily due to the intense heat. I recommend car owners in hot regions to apply window tinting to enhance driving comfort and safety.
