Is there a coating you can apply to the glass to help with smudge marks?

Oleophobic coating is standard on phones and tablets, which is part of why they don’t pick up fingerprints as easily.

Some brands offer coating you can DIY yourself (eg ProofTech OLEOPEL) but these seem mostly designed for phone screens. I don’t know whether they’d be as effective on laptop screens

And this is why modern screens (and eyeglasses) should be cleaned with a damp microfiber cloth and no aggressive cleaners. These coatings are fragile.

I do carefully clean the nosepads with soapy water, however.
