Could I damage the pixels on the monitor?

Question

macbook

Hello. I was sitting at my computer as usual and saw a black dot on the screen of my macbook and like a moron scratched it with a fingernail, it hardly moved away, but after that this place (small dot) shimmers with color as if a drop of water is there, well, as if the pixels are visible.
Could it ruin the screen like that? The screen as a whole works fine, but this dot is in the center and unrealistically infuriates. Is it possible to fix it somehow? Running my fingernail along the glass at this point, I feel some kind of small unevenness there.

I would appreciate your advice.
Thanks

Answer 1

There was dirt on the monitor, and you scratched the screen with your fingernail.
Think so.

Answer 2

Most likely just dirt. Something stuck. According to the description - it can be dried juice from fruits - they ate an apple or watermelon nearby. It splashed and froze. The screen on the retina has a fairly strong coating, I can’t say that it is glass, but it is definitely stronger than a film coating, such as on a Macbook Air, you can’t scratch it with a fingernail if you don’t specifically pursue this goal. A slightly damp microfiber should be wiped off, or just breathe and wipe with microfiber. The kit comes with a good cloth.
