Why Are Some Windshields Tinted Blue At The Top?

Have you ever noticed that some windshields have a blue or green tint at the top? This is actually a shade band, and its purpose is to provide drivers with added protection from glare and UV rays. Automobile manufacturers don’t utilize shade bands as much as they once did, yet some new cars and many older cars are equipped with this feature.

Here’s some more information about this often-overlooked characteristic of windshields:

What Is A Shade Band?

A shade band is a strip of tinted glass located at the top of the windshield. It helps reduce glare and makes it easier to drive into the sun. It also helps protect your car’s interior surfaces from fading due to UV exposure. Shade bands were once found on most makes and models of new cars. Yet, over the years, manufacturers have used them less and less in favor of other features now found on most new vehicles.

Why Are Windshields Tinted Blue Or Green?

The blue or sometimes green tint on windshields serves several purposes. First, it reduces glare and makes it easier for drivers to see when driving into the sun. Second, it preserves interior surfaces by blocking out harmful UV rays that can cause fading over time. Third, it keeps interior temperatures down by reflecting heat away from the car’s cabin. Finally, it prevents eye strain by filtering out some of the bright sunlight that can be distracting while driving.

How Does The Tint Help With Glare?

The tint on windshields helps reduce glare in two ways: first, by absorbing some of the light that would otherwise be reflected off other surfaces; and second, by diffusing light so that it isn’t as harsh or blinding when entering your eyes. This allows you to see more clearly while driving in bright conditions without having to squint or shield your eyes with your hand.

What Types Of Films Are Used For Windshield Tinting?

The most common types of film used for windshield tinting are either dyed, metallic, or ceramic. Hybrid and carbon options are also available. These films have been proven to reduce glare and lessen effects of the sun’s solar energy heating up your car’s interior temperature. 

They also provide protection from UV rays which can damage the vehicle’s interior surfaces over time. If you’re old enough to remember the dashboards of the 1970s and 80s, they were especially prone to drying out and cracking due to UV exposure. One way automobile manufacturers tried to combat this issue is with the utilization of shade bands.
