Little dimples/dents in the Macbook Pro 16" screen?

I have a number of tiny little dimples on my macbook pro 16" screen and I don't know how they occur.They look like someone has stabbed the screen with a needle. I have maybe 10 of them varying in size, all on the left half of the display. They aren't noticeable unless the light catches it but they are quite annoying when that happens. Has anyone else had this issue? How do you prevent it?

I am not rough with my MacBook. I would consider my self to be a very clean person.I actually got the biggest dimple (the last two pictures in the imgur album) last year. I thought it was my bad and I just sandwiched a piece of sand in between the screen. That dimple is very noticeable—there is a black dot on the display. Since then, I have bought a large microfiber cloth that goes between the screen and keyboard. I use this every time I close the screen. I am a student—the only place I take my Macbook is to the library, class, and back home where I dock it. I don't know how it continues to spawn more little dimples, especially with the microfiber cloth.

Update 1.25 years later:

New Macbook Pro 16" m1. Many more dimples/dots than I've ever had. I am meticulous and religious about wiping my screen and keyboard down with a microfiber cloth *every* time I close it. They still appear. Awful
