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.

Yup I've had also had some show up in the past while (got it checked out to make sure no concerns), and looking at a very bright screen makes them _very_ apparent. I already preferred a darker screen but this just sealed the deal.

This 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 a system setting also means I spend less time having to re-style sites with a browser plugin.

This is probably already an endless back and forth like the editor wars but I'm okay with that as the long term status quo. It'll mean that most designers learn that they just have to use themes and include an option for either preference. Some even go as far as making their sites look good in both modes. It pleases my counter-culture senses to see them exploring more angles on the color wheel.

Eh, I prefer dark mode aesthetically, and also I personally find that, at 4 am in a dark room where the only lights are a single desk lamp behind my monitors, and the monitors themselves, white backgrounds are painful. I’m willing to accept that if I was in a sunny room at high noon that light mode might be better.

They used to say it was bad for your eyes to watch TV without having a lamp on in the room. Looking it up now, it sounds like it causes eye fatigue but not damage.

Yeah, having some back lighting definitely helps prevent eye fatigue. I can't do staring at monitors in a pitch black room anymore like I used to when I was in high school. Nowadays if I do that my vision gets,,,squishy.

Yes this is also because these days monitor engineers optimize for peak brightness and totally neglect minimum brightness specs. Because 600 nits looks great on a spec sheet and it's just difficult to regulate (backlight) LEDs over a huge brightness range without affecting color accuracy or causing excessive flickering. Nobody looks at the minimum spec if it's even provided.

So what they tend to do is to have the low end of the brightness range way too high and often even use tricks like simply displaying a darker image (Rather than a darker backlight) which reduces color depth and accuracy even more.

I use my otherwise excellent LG 24UD58 with brightness at 0% during the day! So during the night it's way too bright.

You can accomplish this also by setting the contrast to a low value on screens where the brightness simply doesn't go that low. But some screens just incorporate this trick in the brightness control themselves. Also you can use software options of which dark mode is one. However all these methods (with the exception of dark mode!) result in screwed up color depth (and thus excessive banding also) and dynamic range.

I grew up with white on black displays but these days I prefer black on white because it's easier to read with eyes that have astigmatism. But I end up using dark mode at night anyway because otherwise my display brightness just isn't bearable.

What doesn't help is that I live in a hot country with no AC and during summer I usually live with the windows open at night and the lights off to avoid attracting bugs. So it's difficult. I really wish display builders would optimize for low brightness more.

Light mode for me, always. I just lower the brightness level in night/dark settings and when in bed.

I actually had to learn advanced config editor in Firefox to stop websites from forcing dark mode without alternative.

Lunar plug https://lunar.fyi/?source=lowtechguys Unrelated to dark mode, but is a visual game changer. People should also take the time out to get appropriate light bulbs for their studies and work desks. I want to speak more on visual settings in web design and GUIs, but I’m eating some corn chips. In brief, I’m starting to understand that accessibility concerns don’t refer exclusively to people with certain conditi…

>get appropriate light bulbs for their studies and work desks. What are these?

You know like in lamps or light fixtures. Get the right color temperature for your surroundings and needs and what not.

For example, for some deranged reason I felt that it was appropriate to have my entire study engulfed in Daylight lightbulbs. The three bulbs in the ceiling fan and the tall lamp next to my desk. Daylight. I must have figured, “Man, I do a lot of reading”, or something like that. Daylight.

This went on for quite sometime. I would often receive comments about how the lamp would serve better for interrogations, but I kept on with this setup until I got a monitor for my laptop. This required a non-impeding alteration to the layout of my desk. The height and bend of the lamp had to be changed, I had to change how I sat to accommodate how I looked at the monitor, or when I was using both the laptop and monitor. Stuff like that.

It wasn’t until my right eye began to feel dry that I decided to make a change. So I spent some time learning how to choose the right lightbulb. I did not need daylight. I was not in a restroom or operating a security camera. I needed something warmer. So I got something warmer and I use Lunar.

> Unless you’re using an OLED or AMOLED screen and your dark mode is truly black – not dark grey, not dark blue, BLACK. There is no difference in power consumption. Depending on the file I guess mini-LED could also consume less power with a dark theme, right? If a whole region could be dimmed. Is it true that an OLED displaying a dark color uses the same amount of power as one displaying a light color? I mean, clearl…

Seems right for microleds. However two years ago they weren't much of a thing for consumers. I think they still aren't in any significant way? Samsung has those massive microled tvs but I thought oled still reigned as the current king.

Err, I think I was thinking of mini-leds (edited in). Which are the ones that, for example, Apple uses in their laptops?

All I can say is :shrug: As soon as I left the comfortable worlds of Apple ][ and MS-DOS and got shoved into Windows 3.0, I pined for a dark screen and started fucking with the color profile. When I was 12. When I started running Solaris and Linux boxes in college, always had a dark terminal, and wrote my code in vi. The older I get, the more I crave the darkness, and the UX bros are accommodating me. Maybe it's just…

This was certainly true in CRT times, but since the advent of LCD I prefer light mode, and it is easier on my eyes (as long as the brightness matches the ambient light). Only with OLED do I prefer dark mode, at night, at least on mobile devices (haven’t used an OLED desktop yet).

> By default, the human pupil changes size depending on the amount of light in the environment This is the key: Do you work on a very illuminated place? Use light mode. Do you work in somewhat darkness? Please use dark mode. At least that's what I try to follow, otherwise at the end of the day my eyes gets very tired.

One should always adjust screen brightness to the ambient lighting. If ambient lighting is so low that an accordingly “bright” background provides too little contrast for black text, then yes, dark mode becomes preferable. This is probably a similar point as when printed material becomes too difficult to read. But the other option is to just not work in such a dim environment.
