Is it necessary to apply rear window film for cars?

[DiJaxon]

Applying car window film has both advantages and disadvantages, and individuals need to weigh the pros and cons before making a decision. Below is a detailed introduction to the relevant information: Disadvantages: Affects visibility. Applying film to the side and rear windows of a car can significantly impair the driver's field of vision. Especially at night, it becomes difficult to spot vehicles without headlights through the filmed rearview mirror, which can easily lead to traffic accidents. Advantages: Blocks UV rays. Medium and long waves of ultraviolet rays can penetrate thick glass, but applying heat-insulating film can block 99% of UV rays. This helps prevent skin damage and reduces the aging of car interiors. For example, the Mocha front window film MA70 can block 99.9% of UV rays, equivalent to 56 times the SPF40 of sunscreen, making it a product recommended by the American Skin Cancer Association.
