They absolutely help my eyes not be so strained. If its placebo, its a working placebo.

>Are people actually using Night Shift? >Aggravatingly, yes.

What is the authors problem lol? It feels a lot better on eyeballs to use warm light things. Why does he care?

I find it somewhat pleasant, but by far the best thing I did to help my eye strain was greatly lower the brightness. Basically, I was told to make it so that my phone's camera could see something on the screen and my desk at the same time without washing out.

After doing that, I have found that the "temperature" of the screen doesn't really matter to me that heavily.

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 started spending a lot of time in front of the screen. I went to an optometrist who tested my eyes and told me I could get low prescriptions (.5) but warned me that there's no way back and that many people are fine with my current vision, choosing not to get a prescription. Luckily I figured out that it was blue light that was bothering me and once I turned it down I haven't had any problems since. I'm in my mid 40s and my vision has naturally deteriorated a bit but I am still fine with no prescriptions.

And I don't believe this to be placebo. Every time I stare at a regular screen for longer than 5 minutes I get eye strain. At the same time I suspect this doesn't help everyone, but at least to me this is a great solution that still works.

Aggravatingly, you can't set Night Shift to actually be on 24/7. It always has a "seam" where it fades off and then turns back on.

One trick is to schedule this as a bedtime reminder to put down the phone for the night (phone fasting).

I actually cannot use my monitor without nightshift, any white page just makes my eyes water, painful even. I had it off for a day when I switched to linux and immediately my eyes started drying out.

Safe to say it works for making your eyes less tired at least.

Are you sure you are not also changing total luminance?

My Windows 10 PC glitches out most days where the 3rd monitor doesn't properly apply the Night Light setting. So I turn it off and on to fix it. The full blue brightness is awful and definitely harsh on my nighttime eyes. I'm not sure I could believe it's placebo

It is a placebo, it is an aesthetic thing. It is not something that helps anything at all physically.

This was always well known. It didn't matter 5 years ago, 10 years ago, when OS added it. Easier to let it go than argue.

But with HDR, it matters enormously people are well educated on this. Monitors are approximately light bulbs, and we've gone from staring into a 25W light bulb to a 200W one. (source: color scientist, built Google's color space)

I think it's better to avoid stuff like this. Been here 16 years and a flippant "whats his problem" "lol" and "why does he care" is 99th percentile disrespectful. It's not about what you're arguing, its just such a fundamental violation of what I perceive as the core tenant of HN, "come with curiosity." You are clearly curious, just, expressing it poorly.

I'm not an MD or expert in this field enough to know if OP is right or wrong, but I think it's fairly reasonable to be irritated people are claiming software has a health benefit based on vibes/feels.

I thought we as a society had moved on from superstition to evidence-based medicine, but in this very post there are plenty of replies countering OP's scientific analysis and data with anecdotes (which is disappointing regardless of if TFA is correct or incorrect).

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.

I love Night Shift.
