I like dark mode very much these days even during the daytime because I find staring at a bright white screen runs the risk of triggering a migraine. Dark mode screens don't do that. The contrast between pure white backgrounds and pure black text is too stark and causes greater eyestrain when it's directly transmitted light as opposed to reflected light. Displays in light mode that are reflective do not have this kin…

https://www.nature.com/articles/s41598-018-28904-x Proposes that black on white text stimulates a pattern of expression in visual system that may contribute to myopia: > Using optical coherence tomography (OCT) in young human subjects, we found that the choroid, the heavily perfused layer behind the retina in the eye, becomes about 16 µm thinner in only one hour when subjects read black text on white background but a…
Careful there you got the conclusion other way around. You said WoB contributes to myopia. Your own source says WoB inhibits myopia.

#163This post seems to boil down to, "I read a summary of one study, so I am confident in telling you all how wrong you are". Thanks but I'll let the scientific process play itself out over time. In the mean time, I appreciate that the public debate has induced phones, apps, and many web sites to give me the option to enjoy reading things all day without eye strain. The fact that more stuff defaults dark mode or follows…
I think your summary here more or less applies to the entire debate, and many other similar debates. When did we forget that personal preference an entirely sufficient reason to make a personal choice? I don't use dark mode because a meta-analysis of opthalmological studies indicates it may improve eye health, I use it because I like it and my eyes feel more comfortable using it.
It's ridiculous to think that all our eyes are the same, and that some study can determine what is best for everyone.
And it's not that I've only used light modes and don't know any better. Our eyes and preferences change over time.
I grew up on what might be called "light modes": Teletype paper with black print on yellowish paper, and then punch cards and 11x13 fanfold paper with the white and green alternating stripes.
Later I spent many years using "glass teletypes" and the IBM Monochrome Display, both with green-on-nothing. I guess you would call that a dark mode.
When I started using Windows in the mid-1980s, I adapted to "light mode", but I had to turn the background down to a medium gray because even on a high end CRT display of the day, the flicker was so awful and it was less noticeable with a subdued background.
Then high-quality LCD displays came along and the flicker went away. Around the same time, my eyes were changing. I developed astigmatism, and even with good single vision prescription lenses (a must!) I found that text was much easier to read in a light mode. Perhaps for the same reason that I now have more trouble driving at night than I used to.
There is one bit of science to this: the light background causes your eyes' irises to stop down, and just as with a camera lens, this can result in a sharper image than a wide open aperture.
But again, my eyes are not your eyes, and I'm not disputing your preference for a dark mode.
I will say that one key to using a light mode successfully is to turn the brightness down. And maybe turn your room lighting up a bit. Someone else in the thread mentioned this, but a white background on your screen should be about the same brightness as a white sheet of paper in the same lighting conditions.

#164I was a big believer in dark mode for a long time, until I started trying to reduce my SAD symptoms during the winter time. I read this blog post here [0] after seeing it on HN, and ended up buying 28 100W equivalent bulbs and a 500W equivalent corn bulb. I get a pretty decent amount of light in my home office now, and light mode is essential on my workstation or it's almost impossible to even SEE anything on screen,…
Make sure to get a high-CRI led, that’s what really makes the difference in my opinion. Cheap leds will have a narrow frequency band, high CRI is what makes the reflected light feel more real.
I use a cpu heatsink with silent fan to keep the led cool.

Like you, I found a huge improvement in mood if I use light cues to help convince my body that I live in an eternal late spring. So far I've used Hue bulbs, as I love their color temperature range and the ease of programming. (For me it helps that a plausible day-night cycle just happens in my house.) But I've wondered if daylight-like lumens would be even better. And Hue is cost-prohibitive for that level of light.

There are many sources for each. Web search or https://hn.algolia.com should find them.
I'll take that as a "no." I appreciate the summary anyway, thanks.

I just went to Home Depot and bought the 8-packs of 100W (13W) equivalent, 5000K, 1600 lumen non dimmable LED bulbs from Feit Electric. Screwed those into a 4-Way light ceiling fan using 4 7-way splitters.
I bought a big 10,000 lumen, 100W corn bulb (with no fan) at a Menards, and screwed that into an old floor lamp I had sitting around. This was actually my first try before I did the wider array of lights, but it wasn’t bright enough by itself. The light from this is also “dirtier” and depending on your webcam it might show lines as it’ll refresh at 60hz or 120hz or something like that, and make your Zoom calls look like you live in a CRT.
I know a lot of people talk about high CRI bulbs when you get into the weeds in this sort of stuff, but I didn’t want to make perfect the enemy of good here.
If you spent a little more you could buy dimmable bulbs instead, although it’d probably be easier depending on your hookup to just selectively shut off some of the bulbs to accomplish the same goal.
More holistically, for day night cycling, I’ve also started taking 0.3mg of melatonin (don’t take more than this, your body doesn’t need it, google it if you’re interested). I’ve found it helps me get to bed earlier and stay asleep until morning, where I’d wake up sometimes.
