A metaphor for someone viewing something in the past as much better than it actually was refusing to remember how bad something may have been.
People wearing
nostalgia goggles usually wanna go back in time & live in a certain period again, forgetting everything wrong with that time period.
Nostalgia goggle users often prefer old crappy versions of TV shows & movies they grew up watching rather than the new & improved versions.
Ex 1: a Dragonball fan who grew up with the Ocean
Dub that hates the
Funimation dub for being different is wearing nostalgia goggles, refusing to admit the Funi dub is much more professional & authentic than the amateur sounding Ocean dub.
Ex 2: a woman who grew up watching My Little Pony who hates Friendship is Magic for being different has a bad case of nostalgia goggles.
Ex 3: an old person who thinks the 1950s were much better than the present day in every way & wishes to go back is wearing nostalgia goggles, forgetting that we had half the conveniences, technology, development, infrastructure, movies, etc we do today.
Example:
Old Russian: our
motherland isnt what it used to be. I miss the Soviet Union & I think we should go back. Turn full communist again & take back the republics.
Normal Russian: I agree some things were better back then but take off the
nostalgia goggles. We were like North Korea back then. This was a terrible place to live, we were just more unified & patriotic then.
