Is it normal to feel dizzy after applying new car window film?

[Elliott]

Feeling dizzy after applying new car window film is not normal and is usually caused by poor-quality film provided by the service provider. The main issue is uneven thickness across different areas of the film, making it act like a convex or concave lens. Such film refracts light in a way that conflicts with the driver's myopia or hyperopia, leading to dizziness and nausea. Here are some post-application precautions: 1. Avoid rolling windows: Do not roll down car windows for one week after application. Typically, car window film takes 5-7 days to fully adhere to the glass. During this period, minimize window operation to prevent film displacement. 2. Avoid wiping: Do not wipe the film for one week after application. Newly applied film often develops fogging, which is a normal drying process phenomenon. This condition usually lasts 1-2 weeks until the fog disappears naturally - do not attempt to wipe it away. 3. Avoid sharp objects: Never use sharp or rough tools to scrape the film after application. Such contact would significantly reduce the film's light transmittance.
