So buy 5mg, and split the tablet in half.

that'd give you 2.5mg, which is still almost 10x more than what I linked. it's possible to split and separate them enough of course, but beyond "roughly half" it gets rather difficult. I've considered getting the liquid ones and a micro-dropper for smaller doses (if they'd even be small enough, many combinations are not), but 0.3mg pills are rather convenient and worth the small amount of money for me.

Oops, missed the decimal position!

because if you read the article its about blue light filters to aid sleep not ease of reading. The the grift wheel on this particular bandwagon is strong. To the point where my fucking glasses have a blue filter on them, which fucks up my ability to do colour work becuase everything is orange.

Blue light filtering lenses come at a premium. You don't accidentally get them.

I wasn't paying for them, so it was very much accidental.

Someone ran up to you and put them on your face?

I bought some amber glasses from blublocker.com[1], because they link to a research paper that actually measured how much of each wavelength their filters allow (as well as other brands). They're pretty dark, so you have to crank up the brightness on your screen, but I'm confident that I'm not getting ANY blue.

I have Night Light perpetually on with all of my devices because I find it softens everything and makes viewing displays less harsh, less garish, less vivid, and less intense. I don't need eye searing HDR constantly cooking my retinas.

I confirm that this helps me as well. Quite often I don't have any fancy filter, I'm permanently setting display/monitor to low temperature and my eyes/vision couldn't be happier. I don't even need darkmode, regular mode works just fine for me as long as blue light is toned down. Granted, I'm not doing any color correction or anything color sensitive work. I used to have terrible headaches about 20 years ago when I s…

Can you elaborate on “no way back”?

You should go back and demand they be replaced. Such a mistake isn't something you should tolerate.

Night shift seems to have a very strong causal effect on my sleep cycles. Up until about ten years ago I was a night owl, rarely falling asleep before midnight and rarely waking up before 8. Then I started getting serious about light hygiene and using night shift and now I'm a serious day person, rarely staying awake after 11 and rarely waking up after 7. But the real clincher is that when I travel I don't change the…

The OP article is primarily about separating the variables you lumped together.
