On the advice of a 19 year old (I'm 60) I tried using the polarized sunglasses i keep in my car, at night.

I helped.

Ida know, can someone comment on whether that actually does reduce noise in whatever information is needed to drive safely?

I would suggest you check your eyes as well.

Age progressively adds deposits in the lenses in your eyes, and at some point cataract surgery replaces the lens with a clear one.

Thing is, these deposits work like a dirty windshield in sunlight - you can't see because of the glare. The glare is just off-axis light hitting a surface and scattering - it illuminates the entire surface reducing contrast.

The more deposits and/or the brighter the light, the more it behaves like an completely fogged windshield.

(there is also another kind of glare that affects young eyes - a very bright point of light can cause pain in the retina where it focuses)

Not polarized since glasses, but I've start wearing specially made night driving glasses at night. They have a yellow tint, and so they strive to reduce glare. Doesn't solve the issue of some asshole in a Tesla who tunes his lights to be aimed as high as possible, but it helps
