>Use a clean microfiber cloth. ANYTHING ELSE will scratch your lenses up.
No, it wont. I'm cleaning mine for decades with anything at hand (cotton shirts, napkins, etc) and not a scratch.
And of course there's the little fact that microfiber cloth is a recent synthetic thing. People used cotton and linen squares, or chamois leather ones if they felt fancy, to clean their glasses.
but glasses were made of glass, and nowadays most are plastic.
They’re also typically covered in hard anti reflective coatings. Making them similar to glass in scratch resistance.
