I suspect many here wear glasses and have experienced this.
You clean them in the morning, put them on your face and some hours later they are gunked up. Maybe not badly, but noticeably (I am particularly sensitive to it but that’s just me).
How does this happen? I am not “wiping my eyes” with glasses on and hitting the glasses. It’s like some crud flies off my eyes onto the glasses. But I don’t think that makes any sense. (the inner side of the lens, closest to my eye, is usually the more smudge part).
So why do I have to clean my glasses so often?

You kinda answered it in one: you are blinking your tears onto your lenses along with the filth on your eyelids and lashes. Your eyebrows are no help, either. Dust in the air finds a happy home on your specs. It’s a miracle we can keep them clean for _any_ length of time. Get wiping!

I wonder at the crap on my glasses too! Seems like it’s on both sides. So if I didn’t wear glasses, stuff would be flying into my eyes all the time?
I also would like to know why they’re so damn scratched. 🤓

I’m pretty sure my eyelashes are not brushing against my glasses. I have felt that happening and it drove me nuts. I am sure to wear my glasses far enough away to not be brushed by my eyelashes.
Blinking tears on…maybe…lots to be sad about these days.

Your lashes are tiny slingshots, flinging crud onto your lenses. Comforting, yes? Plus, ya got oils on your eyelids and that whole area is shedding skin cells and I’m getting grossed out just thinking about it.

That has to almost certainly has to happen when you take them off and put them down. Or put them in your pocket or wherever. That is where they get scratched.
Glass lenses are more resistant but not sure you can get those anymore (probably can).

Mine don’t gunk up anywhere near that fast. Maybe you are touching the lenses when you put them on and take them off, or are touching them at some point and not realizing it?
I probably clean my glasses about once a month. If I were “particularly sensitive” (as per the OP) I would probably clean them about once a week.

Some of the aforementioned gunk that accumulates on your lenses can have really sharp edges that leave gouges when you try to wipe them off. Gunk loves living on yer glasses and it’s not leaving without a fight.

I feel your pain. I clean my glasses morning, noon, and night, and in between. I often rinse them off with soap and water and dry them with a tissue, which is made from wood pulp and is notorious for leaving tiny scratches. I don’t care, I get a new pair every couple of years, so the scratched ones will be my old emergency glasses in the drawer.

Either you have some super-duper-teflon glasses or you are really not sensitive to smudges.
I have met people who are not sensitive to smudges on their glasses. Drives me crazy when I see it (if I can through my smudged glasses).
MUST be cleaned! 🙂
I honestly cannot imagine daily wearing glasses only cleaning them oncer-per-week (or less).
YMMV of course.

He’s probably engineered some negative electrical charge onto his lenses that repels invaders.

I take my glasses into the shower with me, and thoroughly wash them using soap, water, and a washcloth. I pay particular attention to the rims of the glasses, since that’s where the dirt & oil seems to accumulate. Afterwards I’ll clean the glasses with an alcohol-based wet wipe.

My glasses are always getting dirty.
I try to only clean them once a day or when they become visually distracting.
Sometimes by the end of the day I feel like I am looking out from the window of an abandoned house.
I have dedicated cleaning cloths and try not to use tissues if at all possible.
Inevitably I wind up with a scratch or two despite taking great care.
Maybe it’s just me but it seems that the quality of the glasses has gone down over the last 10 or so years.

My hypothesis is that most scratches are due to improper cleaning. If there are fine particulates on your glasses, “cleaning” them with a wet or dry towel will cause the particulates to be dragged across the lenses, and the pressure on them from your fingers will create scratches. You should first try to remove the particulates by running water over the lenses.

glasses that magnify, magnify the small particles making them noticeable. depending on your nose and cheekbones your glasses could be resting against your face.

I clean my glasses with an ultrasonic cleaning device for glasses about every two days. It works very well and doesn’t leave any scratches.

Rinse vigorously under running warm water then wash with dishwashing soap. Cuts the skin grease & removes particulates before you grind them into the lens.
For me, my glasses often rest against my eyebrows. Thats where most of my gunk comes from. Putting them on & taking them off tends to spread the gunk. It’s also easy to brush the lens w my hand unnoticed while adjusting them on my nose, scratching an itch, wiping mouth, etc.
I wash them daily. Because they need it if I wear them all day.
I doubt my experience is too far from typical.

It’s them nasty pesky little eyelash mites trying to jump ship.
Catch that ride on your glasses.
They have other folks eyelashes to invade.

I remember during the COVID pandemic reading that it is vital to wash one’s hands because the average person touches his face over 50 times per hour. Since one’s glasses are on one’s face, they must get touched a lot also.
