Going below 50% brightness on _most_ monitors brings the flickering into the realm that many humans can perceive. This is because the physical brightness cannot actually be controlled, so PWM is used to adjust perceived brightness.

That is not true for many displays. Have a look at reviews, whether there is pwm control/flickering is part of all(?) professional reviews now.

Terrific, that is great to know. I might update my monitors if so.

I have lots of eye floaters which annoy me when I'm looking at bright uniform surfaces, such as white paper or white background, but I hardly notice them with dark mode.

Same. They don't bother me in every day life at all. Stick me in front of a white screen though and they become incredibly distracting,

Fascinating, I’d be interested in seeing what ten or even twenty of these could do to a room. I’m curious how many lux I could get in a room without tripping a breaker. The added benefit is I don’t have to run a space heater!

Honestly, a single 50W led is more than enough for an office sized room. That’s not a lot of heat. We’ve got 16A circuits at 220V here, so you could do about 70 of those before tripping a breaker :D

You're talking about something very different than the original poster then. They mentioned something more in the 400 watt range. I have around 70 watts of LEDs (split between 7 bulbs) in my small office (7 square meters), and am considering boosting that significantly.

50 watts I would put in the range of "normal bright lighting" (it's approximately the equivalent of one halogen floor lamp). 400 watts gets into "trying to simulate sunlight for therapeutic reasons"-territory.

Changes are good!

Sometime, when I want a change of perspective, I switch to different theme for a couple of days/weeks/months and then change again, and again, and again...

I've noticed just changing the theme can help refocus.

It is a bit like changing the layout of your house to bring changes to your life.

(only it's so much easier with M-x customize-theme)

>When I was in the military, a key tactic of camouflage was to never, under any circumstances, expose yourself on a hilltop or similar, where your silhouette could be easily identified. A dark blob on a light background is far easier for the human eye to see, than the reverse.

This is a strange argument for dark/light mode. It might be easier to see, but can you imagine how tired your eyes would get if you were looking for/at dark blobs on a hilltop all day? I wouldn't last an hour.

I'm fine with this guy preferring light mode. I've tried them both for many years each and I much prefer dark mode for my own well being.

> OMG didn't expect to see the "I know this is true and I don't need researchers telling me otherwise" argument here. And, you didn't see that here. That you would even think that shows that you didn't read what was written. It is ridiculous to wait for what others say about whether dark or light mode strains one's eyes more, since each person already has a pair of eyes to test what works for them.

Can I interest you in some homeopathic remedies or a bottle of snake oil? Maybe prayer? History is full of people who thought/think their bias and anecdotal evidence is good enough.

Those are some very poor comparisons. Maybe if someone is claiming that dark mode or light mode have long-term effects on your health, but what people are actually claiming is just that they find one or the other more comfortable. There’s no meaningful scientific “truth” to that beyond a person’s own stated preference, just like there’s no scientifically most comfortable pair of pants or best color of wall paint. For what it’s worth, my preference of pants is definitely biased and based on anecdotal evidence. I have a pair of legs to test it with myself.

In my stint in factory automation, the night mode vs day mode acceptance dependent heavily on the light properties inside the factory. With flooding daylight, the only thing acceptable was light mode, with artificial light - controlled light, usually used to decouple the workers from theire feeling of time or in nightshifts, the dark mode was prefered.

So my theory is, dark mode is prefered, were irregular times or crunch is prefered. Lightmode is in open, daylit offices or home offices, were you value & keep track of your time and life.

I've read a couple of other posts about this (below) so I finally decided to give light mode a try for a week. I've switched to all Solarized Light terminal/editor/Firefox/GTK and turned off dark mode in the websites where that's a setting. https://stitcher.io/blog/why-light-themes-are-better-accordi... https://medium.com/codesphere-cloud/should-you-really-be-cod...

Solarized Light was my gateway drug to light mode, and I later switched over to using Modus Operandi in Emacs, which really made me appreciate proper light themes. If you use Emacs and/or Konsole you may like it.

Such odd arguments, it's very simple to me. The problem is really that we like to work late, with bad lighting.

All this would be resolved if we had proper lighting, as is mandated in every Swedish office in fact.

But I like working late from home, so I have very poor lighting a lot of times. Therefore bright applications and websites hurt my eyes more than darker ones.
