Is it okay not to apply film on car windows?

[SanMalachi]

It is not advisable to leave car windows without film. The impacts of not applying film are as follows: 1. The front windshield is the main source of heat radiation that raises the temperature inside the car. Applying a transparent film can significantly improve the driving environment and reduce air conditioning energy consumption, thereby achieving energy-saving effects. 2. After applying film to the front windshield, it effectively blocks UV rays, protecting the dashboard from radiation and extending its service life. 3. Since the front windshield is made of tempered safety glass, applying a front windshield film prevents glass fragments from scattering in case of breakage, ensuring the driver's safety. 4. However, if non-specialized front windshield film is used or the installation is poorly done, it can severely affect driving, especially the driver's nighttime safety. Generally, after applying a high-quality transparent front windshield film, there will be no light reflection patterns when driving through tunnels, nor any glare from oncoming headlights during nighttime driving.
