I, too, find headlight glare a problem, I’m ok on dual carriageways and motorways but single track roads I find increasingly difficult. I have had an anti glare coating on my distance glasses but the main reasons are age, glaucoma and the beginnings of cataracts. I am told that I will probably need the cataracts to be dealt with in about 3-5 years time.

As for headlights, my car (not an SUV) has LED headlights and as long as they are correctly set, they should not dazzle oncoming vehicles. The problem arises with aftermarket LED headlights, most of which originate in China, and they are cr@p, the beam spreads, unlike OEM lights. Unfortunately, original brand lights, in my case Ford, are expensive, a lot more than the cheap Chinese rubbish. If people set their own headlight level, they will probably set them too high and too straight and thus will dazzle oncoming traffic.
