Yes, they can. I have several images burned into my retinas.
I've seen things online that can't be unseen.

[Sieger]

If you smack your eyes with your screen hard enough then of course

my parents when I play 1 hour on my playstation: you will go blind..

also my parents: watch 3 hour movies again and again.

I'm such a big fan of dark mode on all my apps. Definitely a big difference when using my phone a lot.

Well... it adds another level of meaning to the Blue Screen of Death...

its not the blue light that kills you, its the habit of sitting at one place and chilling all day that kills you

I have a feature on my laptop called "Night Light" which changes the light from blue light to warmer, yellowish colors. Does this counter the effects of blue light screens?

Great video, good to know that I can now watch as many sci show videos in a row as possible!

I have a suspicion that it's about focal length, not about the light from the screen. We are focusing on things that are a lot closer to us for a lot longer than humans used to have to. It may be contributing to nearsightedness.

0:03, ha! That's where you're wrong! I'm watching this on a projector.
