The adblocker settings can also be used to block various distracting content recommendation sections of sites you frequently use, if you want to just see the content you explicitly wanted without having your attention hijacked/tempted with clickbait from the same site. On some sites you can configure it in some options, but for others a simple filter can do it.

For example, for me the youtube shorts section, or the stackoverflow 'hot network questions' section are things like that; they are "almost ads" in some sense.

Would love to see links to information on how to block some of the particular avenues mentioned. Some I haven't heard of yet.

I use a pi-hole and uBlock Origin, but am always up to learn more...

You could wear glasses with polarized lenses outside. If its rotation aligns with the LCD, you won't see the advertisement on the screen, only a black square in place of it.

I block hostile websites at the DNS level. (This includes news websites that are dishonest or wrong, so almost all.)

I block web content with certain keywords from loading. (How nice would your life be if you never ever again heard about Trump?)

I block channels on Youtube.

I block ads in the real world on my AR goggles. (Soon.)
