Use a clean microfiber cloth. ANYTHING ELSE will scratch your lenses up. (This is probably the most common no-no I see. People will clean their glasses with anything on them and smudge/scratch them instead.)
Two cloths are ideal: one for cleaning and another for polishing.
If you're using soap and water, apply a tiny amount of soap onto both sides of the lens --- less than a grain of rice --- then apply water and rub with your fingers until clean. Skip to polish step.
If using cleaner, spray cleaner onto the cloth, NOT onto the lens. Spray onto one side of the cloth so that you have a wet side and a dry side.
(You can use water instead of cleaner in a pinch.)
Three passes.
First pass: with wet side, wipe lens in lines from top of frame to bottom. NOT in circles. (You'll spread the dirt around this way, making the cleaning process take way longer and potentially introducing scratches.)
Second pass: Repeat first pass with dry side of cloth.
Repeat first and second passes until lenses look mostly clear.
Third pass, if you have a polishing cloth: Wipe polishing clothes in circles until lenses are clear.
Your lenses will last forever if cleaned this way.
The cleaner steps above also work on any glass surface, like laptop screens or car windows.

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.
Yea, this reads very meticulous to me. I clean my glasses under running hot water and the micro fibre cloth. I wash the micro fibre cloth with dish soap from time to time. In a bind I clean the glass with any clean fabric that feels soft.
I don't know why people say this. When I wore glasses I cleaned them with my cotton shirts for over a decade and they didn't get scratched up, at all. I don't see how cotton would scratch glass to begin with.
Usually it's not the fabric but trapped dust that scratches the coating when you wipe.
Dust is harder than hard plastic?

They live in an imaginary world where no one ever cleaned glasses until microfiber cloths were widely available.
To clean glasses safely you basically need a soft, clean cloth. Cotton is totally fine. You could get away with a soft clean sponge, too. Or even a soft-ish piece of paper (which is what most disposable lens words are.)
Most believe whatever marketing material or sponsored "expert" advice is presented to them for "proper care", without actually checking. At least glasses clenaning is a harmless area - people do the same for supplements, diets, and all kinds of health advice too.
