Its a type of glass that has been treated with a material such as a film or coating that reduces the transmission of light through it. Glass can be tinted with various types of coating, which block and/or reflect different amounts and types of light, according to the needs and preferences of the consumer. One of the most common ways in which tinted glass is used is in automobile windows. Almost all cars come with tinting at the top of the windshield to reduce solar glare when the sun is low in the sky. Apart from this, the windows of many cars are tinted either at the factory or as an aftermarket add-on by the consumer, to provide privacy for the car’s occupants, as well as to reduce the buildup of heat in a car while it is parked outside.
