It will be a beautiful day for driving in Texas. Whether you’re driving up I-45 to Conroe, Corsicana, Ennis, or elsewhere.

Perhaps you’ll drive along US 277 for a quick bite at San Angelo’s favorite Mexican eatery. Today’s driving conditions, which include a sunny sky and low temperatures, will be great for hitting the open road.

Every day, drivers in Texas stare through a glass pane to the road ahead. Hopefully, the windshield glass is clear and free of streaks that could obscure your view. Hopefully, you’re not attempting to see through a crack or a star in your windshield, which can be equally dangerous.

You’ve probably noticed one aspect of your current car’s windshield. It appears to be “decorated” You’ve seen some dark trim around the edges of your windshield. In addition to the black edges, there appears to be a series of black dots along the perimeter of your windshield.

Have You Ever Wondered What Those “Black Dots” Are for?

To understand this, you should be familiar with how windshields are installed. In the 1950s and 1960s, producers used adhesives to hold the glass in place. They strengthened the glue by surrounding the windshield with a metal rim. Look at an older car and you’ll notice the metal border.

Modern autos have windshields built in. Yes, baked, like in a cake. And this is when the microscopic black dots come into play. Now, if you thought the “dots” were meant to assist in defog the glass, you were wrong. However, if you assumed that the “dots” were related to temperature control, you were accurate. However, you are unlikely to be “right” about your beliefs.

The Dots Serve Both Aesthetic and Functional Purposes on Your Windshield

The “black dots” are not scattered randomly. If you look closely, you will notice that they become smaller and smaller as you go away from the black edge of the windshield.

This is for aesthetic purposes. It makes the transition from black to clear glass more comfortable for the eyes.

The “halftone pattern,” as it is known, also aids in heat dissipation in the windshield. These tiny dots help to spread heat more evenly across the windshield. This prevents your windshield from warping in high temperatures. We certainly have plenty of those in Texas.
