I finally bought some polarized driving glasses to cut down in some of the glare. They're like sunglasses but bright yellow. They... Help slightly. I'm sure there are some better than the cheap pair I got, though.
Polarization is to cut out sunlight. Headlights do not produce polarized light.
... Neither does the sun. Polarization cuts off all the waves that DO NOT ALIGN with the filter. It reduces the amount of light going to your eye.
Ok the sun doesn’t produce polarized light, but the atmosphere polarizes it. So sunlight is polarized. All sunglasses reduce the amount of light going into your eye…that’s the point of sunglasses.
The light does not need to be polarized for a polarizing lens to have an effect. Polarized sunglasses eliminate glare, unlike their non polarized cousins. This is why they're prized by fishermen-they can see into the water. Works for windshields too.
It really seems like you don't understand how this works.
I don't understand why do many people are utterly baffled by how a filter works...
