ELI5: how do glasses get smudged so fast? Where does it come from and what is it made of?

It seems like I can sit down at my computer with fully clean glasses, and then find myself needing to clean them again after only an hour or so. I make a point to avoid touching my lenses, and am not abnormally greasy or anything.

If it's grease from my face, how is it getting from my skin onto the lenses, since they're not touching? If it's stuff condensing / settling from the air around me, how come I don't notice it on my windows or other glassware?

It’s shedded skin and oil, your eyelashes may be touching the glass.
Acrylic lenses can have a slight electric static charge on them which attracts dust
It helps if you use some wax on the glass after you have cleaned it, dirt can’t stick as easily/
