>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.

yes they do. it's not so much the cotton fabric that will scratch your lenses; it's the dirt on them. cotton weaves leave bigger holes for dirt to get caught in; much much bigger than microfiber, which is why it's best for the job.

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.

You can trivially get glass lenses nowadays. It's a prescription option.

In any case, no scratches on my non-glass eyewear either.

[nunez]

most cheap ones, yes.

if you have vision benefits in the US, you can get glasses with glass lenses for free or heavily discounted

the best optics are glass
