It's noticeable to me all the time, but if I'm borderline migraining, or recovering from a migraine, the difference between shifted and not is something I can feel instantly. Shifting all the way over enables me to eek out some work after a migraine without it flaring back up again.

Absolutely and this is something that can be tested rather easily. If blue filters aren't immediately helpful to eye strain then they probably don't work for you but if they are they probably do work for you.
You can test the negative easily, but the positive is harder. Thus: placebos.

Can you elaborate on “no way back”?
Not OP, but when I got glasses as an adult and while they really improved the sharpness of my vision I could feel my unassisted vision getting worse, so I stopped using them and get by with slightly unfocused but unassisted vision. I assume if I wore them full time my unassisted vision would degrade to the point where I then need the glasses full time.

I meant that once you decide to wear prescription optics you can’t go back to not wearing them, of course excluding eye surgery. In my case I could stick to good enough vision and luckily 20 years later Im still not wearing glasses. My main point was that I was getting eye strain from blue light and once I reduced it the problem dissapeared.
This isn’t true? Myopia develops rapidly in youth then stabilizes in adulthood. It gets a worse with age, not corrective lenses. Then sometime after 40 you flip to presbyopia when your lenses lose flexibility.
You can just do things. Not everything needs a study, you don’t have to justify yourself to anyone! Try things, if you like them, do them! Try not living a neurotic “study” based life, I am trying it and its pretty great!
Otherwise even dark mode is way too bright in a dark room.
I added the “Noir” extension to mobile Safari, now I automatically get dark mode on all websites including Hacker News.
