my back windshield has circles thats are in rows each one is the same distince apart from the nextl. they can only be seen when the car is in the shade or as the sun is about to go down just woundering if any one has had the same problem.

My current car, a Jeep, has that problem in certain lighting conditions only when I have my polarized sunglasses on. Many other cars also have the circle pattern as well. Its pretty annoying and I don't know why its like that but its common.

I believe those circles are the end result of the glass being tempered. A flame is held up to the areas where you see those circles and the end result is stronger glass. Someone correct me if I'm wrong.

You shouldn't see those circles unless you have polarized lenses (artificial, or you're special) Kinda like that Sci-Fi movie with Rowdy Roddy Piper, Them or something like that.
