Automotive window tinting involves applying a thin film to the interior or exterior of vehicle glass. This film alters the transmission of light and heat, affecting visibility, interior temperature, and the appearance of the vehicle. For example, a darker tint reduces the amount of sunlight entering the cabin.
Tinting provides several advantages. It can significantly reduce the interior temperature of a parked car, protecting upholstery from UV damage and increasing passenger comfort. Reduced glare improves driver visibility, enhancing safety. Furthermore, some tints provide added privacy and can deter theft by obscuring the view into the vehicle. The practice dates back to the mid-20th century, gaining popularity alongside advancements in film technology.
