to cut the sun glare... Does not do a very good job.. I wish they had the tint strip made into the windshield like my 07 Accord... I got a tint strip installed for around 60 dollars and it is great when driving into the sun....Ant tint shop can do it...
I have had tint put on my windshield since that picture was taken, I’m just wondering if that thing and/or the window tint would interfere with my tv tuner antenna.

Taken from another website:

One person took to Reddit to ask users why they're there. They wrote: "What are those little black dots that surround my windshield for?"

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."

However, it 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, Mirror UK reports.

The statement continues: "They serve as a contact point between the glass and car frame. They create etches on the surface, making them rougher so the adhesive can stick better to the glass.

"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 revelation, 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!"

Another added: "Ok, that makes sense. But why is it on the windshield, rear windshield, and quarter glass, but not on the operable windows?"

A third said: "I am stunned at the amount that I have learned about frit today."

There is no problem mounting a dashcam with double sided tape on the Frit either, I have done it in a Subaru Forester and 2 Honda's and removed my dashcam from each of them, it is currently mounted in our HR-V.
