Dark themes aren't easy on the eyes. It's preferred when you're looking at a screen in a dark room, but you shouldn't be doing that anyway. When I have to look at a dark theme, I find myself squinting and straining my eyes. Light themes just look better too. Better to save your battery by lowering the brightness of your screen.

Albeit dark themes are more beautiful, in a light environment during daylight, a light background with dark fonts is easier on your eyes.

Because I can't get it consistently. Better to have my eyes adjusted to constant light than be randomly blinded when whatever random site or app isn't dark.

I use both. I always have automatic dark/light mode enabled where possible controlled by sunset/sunrise. If it's light outside I just prefer light mode and when it's dark outside I prefer dark mode. Being in a well lit room it's easier on the eyes to use light theme.

The only time I use dark mode only is for Discord and IDEs.

I'm just used to it, I guess. I've never had an eye strain issue with monitors for some reason. I'm resistant to change. Moving to Lemmy from Reddit was a big deal for me, and not just because I had sunk 13 years into Reddit, just the idea of changing something I'm very used to... there was a reason I still used old Reddit.

EDIT: That said, I spent countless hours on my old Apple IIs with their famous green-on-black monitors.

I just toggle based on time of day / lightness of environment.
I find my eyes are more strained when using light text on dark backgrounds in a light environment (and of course dark text on light backgrounds are a no-go at night). The only exception to this is my phone, where the battery gains from oled makes dark mode the only option for me. I hope Kbin gets a nice light mode toggle that can follow the system theme in the future.

why?

They are Heretics and Miscreants, an Abomination unto GoD who spread their lies about "The Light".

I just find reading on light mode much easier and comfortable, so i use it most of the time. I do use dark mode for programming, it doesn’t bother me there, but for most apps and websites the dark mode feels much more tiring.

both and as long as not grey text on dark theme

Since Thinklight is no longer a thing, how else am I supposed to read my credit card info off the card?

I primarily use dark themes but I do switch to light themes from time to time. To see better, give my eyes a break, or when in a dark room for too long are some examples. Also some apps just don't play nice in dark themes.

I find it easier on the eyes plus I don't use Oled Screens so I'm thinking "why should I block all this light that my backlight produces anyway just so i have something that looks a little more aesthetic?"

Dark theme gives me a massive headache after just 5-10 minutes and I think it's because the text is fuzzier to me. I'm not sure if it is astigmatism related?

Weird thing is that AMOLED dark on my phone doesn't bother me the same way.

Also colors in dark mode when I'm coding seem to blend together more so I am not as quick at picking up visual cues.

while I would say I belong to the dark-theme cult, there are some applications/websites that I cannot get used to them in dark mode. Like github or slack for example in which everything else than they light theme looks strange in my eyes.

I never understood why go dark only? We have a neat feature in almost all the device change depending on the brightness or sunrise, that is the way to go IMHO.

White UI looks nice as well.

Dark mode just looks bad aesthetically, IMO. Maybe it's something to do with my ADD, but I can't focus for long on apps or pages using dark mode. They're boring to look at.

Here to agree. I use dark thème when it gets to night. Shifting automatically for sunrise and sunset, but when reading long strings of text. That’s a no-go, I have to shift into light mode for that exact same reason
