It's optically active material. The same is true of many rear windows of cars, but thankfully not windshields. I'm curious about this difference. Perhaps they're more careful with windshield because they know drivers like wearing polarized glasses.

I recently got a pair of sunglasses (since I had to dispose of my prescription glasses after having cataract surgery). They were cheap, but they were polarized.

I now have trouble viewing the data screen in my car. The one that shows the GPS map and navigation stuff. The polarization shows patterns on the screen that make it hard to see.

I don't see effects on the windshield nor any of the other windows.

I suspect "riot glass" is probably a version of safety glass that resists breakage and doesn't leave sharp edges when it it broken. Purely a guess on my part.
