Have you ever wondered what those those little black dots on your windcreen are for? Many people may not have even noticed them.
But as reported by the Mirror, it turns out they have an important purpose. And, without them, driving would be extremely dangerous.
A statement on Autoglaze reads: "The black dots, or dot matrix, actually help distribute temperature evenly to lessen optical distortion or lensing. This happens when the frit band (the solid black one) heats up much faster than the windscreen's glass, creating an optical distortion that makes either straight lines look curved or bowed inwards toward the centre.
"Those 'gradually sinking' black dots help lessen this phenomenon by dissipating the heat and spreading it out evenly." But this isn't their only purpose as they also help "preserve the urethane sealant used to bond the glass to the frame", meaning your windscreen stays firmly glued in to place.
"They serve as a contact point between the glass and car frame," Autoglaze added. "They create etches on the surface, making them rougher so the adhesive can stick better to the glass."
The statement continued: "Frits are also there for aesthetic purposes. If you look closely, the contrast between the dark band and the transparent glass can look too obvious even when viewed from afar.

"Creating a halftone pattern or dot-matrix allows a gradual decrease in size, making the transition much more subtle and easier on the eyes." Commenting on the explanation, one Reddit user said: "That is brilliant and simple. So simple that it isn’t believable but so believable that it can’t be that simple!"
