Everything said in this threed is very interesting, but now I am

Another option is a hardware filter: yellow glasses. I am unsure if the

I think, you should decide what is better for your sight: active screen
and perhaps dark theme or paper-like reflective display. Some people
complains that particular devices may have annoying flickering at low
screen brightness due to pulse width modulation. Some devices have too
bright screen even when brightness is set to min value.
If it is acceptable to you to limit device usage to reading and
handwritten notes then a e-Ink might be really great. You can extend
such notes in Emacs on a PC later.
P.S. Concerning free PDF annotation tool, I have not tested if it is
convenient and available on Android, but Firefox-106 release notes have
the following entry:

adding signatures.
Almost certainly "edit" in their parlance in namely annotations, not
real changes of PDF structure.
