You know very well that Alaska is such a rugged country that people there never develop cataracts ~ they simply don't get old enough to do that before moving to Seattle (for example).

The answer to the conundrum lies within the realm of the phenomenon called ONCOMING TRAFFIC. If you don't have any, then your primary concern is about what you can light up in front of you. If you regularly have oncoming traffic you should be more concerned with what the other drivers coming toward you are seeing ~ your 747 landing lights might well be considered disturbing!

I don’t look at the ones that are aimed poorly, there is a technique of just using your periphial vision.

I remember the EXACT arguments back in around the early 1980’s when Halogens came out in the US, of course they were in use much longer in Europe.

The country was enraged about these “KIller Headlights” back then. And many people were literally being ticketed because they were using Halogens or headlight conversion kits like the Cibie that used an H4 halogen lamp, I know because I was one of them.
