At MotorBiscuit we are here to unravel the mysteries of car windows. In a previous article we discussed why there are small black dots on a windshield. In another, we showed the secret apple trick on a windshield. Now, for inquiring minds, we describe why car windows are tinted on the top.
What is the tint of color on the top of a car windshield?
If you look at the top of your car’s windshield, you’ll likely see a layer of color tint on the top. Most modern vehicle windshields have a blue or green tint for the tint, while others have a colorless tint.
The main reason for the tinted windshield is to protect your eyes from the sun while driving. However, there are other reasons, which we discuss below. The blue or green tint makes it harder for UV rays and heat from the sun to penetrate the glass. The shade is similar to the shade band on sunglasses.
The tint is part of the production process for the manufacture of windscreens. During the original OEM factory build of a car, no tint is added after the windshield is made. Instead, it is mounted on the windshield on the production line. Carefully fitting the tint to a precise size is crucial. Otherwise, small air bubbles may form between the glass and the shade, as described by Vehicle freak.
For some cars it can be a challenge to see the colored layer, especially when looking at it from a frontal perspective. However, if you look at the top of the windshield from an angle or from below, you can probably see the tint more clearly.
Reasons why car windows have a layer of tint at the top
There are several reasons why car windows have a layer of tint on the top. This includes:
- Reduces eye strain
- Protects the driver and passengers from UV rays
- Protects the cabin of a car from UV rays
- Reduces glare from sunlight
- Helps keep the cab cool
Reduces eye strain
Drivers can get a lot of eye strain on a long drive. The strain is even more important on clear, sunny days. However, a colored windshield helps reduce eye strain from sunlight.
Protects the driver and passengers from UV rays
The sun has ultraviolet or UV rays. Prolonged exposure to UV rays can lead to sunburn and increase the risk of skin cancer. Like sunscreen, the blue or green tint protects people from the harmful effects of UV rays.
Protects the cabin of a car from UV rays
The colored tinted layer on the top of a windshield also protects the interior of your car from the harmful effects of UV rays. Prolonged exposure to sunlight may cause the upholstery of the seats to fade. However, dyeing can slow down and reduce fading.
Reduces glare from sunlight

Have you ever driven a car and the sunlight hit the windshield, making it difficult to see where you were going? With intense sunlight, it can be challenging to view the road and other cars around you. However, the top layer of hue helps reduce this glare – while ensuring good visibility.
A colored windshield helps keep the cab cool
The cabin of a car can get very hot and stuffy, especially in the middle of summer. While not a replacement for the air conditioning system, tinting on a windshield can help keep the cabin in a vehicle cool by blocking UV rays.
Whether it’s to reduce glare and eyestrain, protect against harmful UV rays or keep the interior cool, there are several important reasons why car windows have a layer of color on top.
