Order a pack of microfiber cloths from Amazon for $5 and clean your damn glasses regularly, There’s cleaning fluid on there cheap too if that’s not enough. If they’re tight on your ears, go to where you bought them and get them to adjust them, it’s usually free.

I used to use microfiber cloths, but found that the lenses would get scratched. My optometrist told me that the combination of cloths and the gritty dirt was the equivalent of using fine sandpaper on the soft plastic. She recommended using a tiny drop of dishwashing liquid on each lens and then washing them with water followed by thorough rinsing. Then dry the lenses by dabbing them with tissue rather than rubbing them. My glasses now last for years with no scratches.
