It is possible not to apply film on the front windshield, but it is still recommended to apply film if conditions permit. The functions of glass film are as follows: Heat insulation and sun protection: The film can effectively block a large amount of heat generated by infrared rays. UV protection: When choosing a film for the front windshield, the higher the UV resistance index, the better, as it can protect the components of the dashboard from premature aging caused by prolonged sun exposure and also protect the skin of the occupants from harm. Reducing fuel consumption: The front windshield is the main heat radiation area that causes the interior air temperature to rise. Applying film can improve the driving environment inside the car while reducing the energy consumption of the air conditioning, achieving a certain degree of fuel savings.

With over twenty years of driving experience, I've personally witnessed the safety risks associated with window tinting. While it's entirely possible to leave the windshield untinted, it depends on the circumstances. In my city, traffic regulations strictly prohibit dark tint films on front windshields because visibility can be severely compromised during nighttime or rainy conditions with insufficient light—I've experienced several close calls with emergency braking nearly leading to rear-end collisions. Nowadays, policies increasingly emphasize driving safety, and traffic police will issue fines if caught. I recommend opting for clear or lightly tinted films that block UV rays without impairing vision. Remember, while films provide heat insulation and sun protection, safety should always come first. I regularly inspect my windshield to ensure optimal clarity.

I mainly focus on practicality when it comes to my car. The front windshield doesn't necessarily need a film, but it depends on personal preference. After applying a high-quality heat-insulating film, the interior temperature dropped by about ten degrees in summer, so I don't need to turn the air conditioning to maximum, which also saves energy. However, some films are too dark and can affect reflectivity, making visibility worse when reversing. I've tested various types, and a light anti-glare film works best without violating regulations. I recommend avoiding low-quality films, as they tend to bubble or turn yellow. Keeping the glass clean regularly can extend the film's lifespan and reduce the risk of chipping.

From an economic perspective, whether to apply window film is a trade-off. A full set of film costs over a thousand yuan, so if the budget is tight, it's better to skip this expense. However, in the long run, not applying film increases air conditioning fuel consumption, leading to higher fuel costs in summer. I've calculated that it could add up to several hundred yuan more per year. Although high-quality film is more expensive, it may save on electricity bills and protect the interior from aging. I opted for partial application of clear UV film, which is more cost-effective and practical. Regular car maintenance is key, and the money saved can be more wisely spent on other upkeep.
