The eyes are adapted to see daylight levels of light during daytime. If your ambient lighting and screen don't match this, then you're not using your body in the way it's evolved to function. What we need more of are screens with anti-glare and a wide range of brightness levels.
What might have a worse impact on your eyesight is the effects of Myopia, which is being exacerbated by basically every portable device with a screen. Anyone who has the technological literacy to enable dark mode (and advocate for it) is likely someone who gets above-average screen time and is therefore someone at a higher risk of myopia.
Well, I'll meet the dark-mode people halfway, and say that it should always be available to users who want it.
No one is saying that a personal preference for dark mode is invalid, just that it shouldn't be the default option, or worse, the only option.
Isn’t that already how it works in all major operating systems?
I think the debate comes down to how bright you keep your environment.
OP likes bright overhead lighting and confuses that preference for the superiority of a preference downstream of it. Yawn.
I’d rather look at a bright 27” screen in dark mode where I see full color fidelity than dim the screen so that bright backgrounds aren’t too harsh. But it’s just a preference.
There are easily 10x if not 100x as many sites that only support their default of light mode as those that even offer built-in support for dark mode, and it's more like 1000x as many as those that default to dark mode.
TFA does seem to be explicitly demanding erasure of the preferences of an insignificantly tiny minority of websites.
Hate the dark.
Dark is hard to see. Light is easy to see. I use light at every opportunity. Dark partially grew out of an interest in saving battery power on early oled screens, but dev's noticed a certain demographic drawn towards the dark look.
Light mode is lower contrast for me, and is more difficult to read text, especially at the end of the day.
Dark mode is a relief, and much easier to read for me.
I miss it in the situations when it is not available, like PDFs with small grey text on a white background, more so on a small screen like a phone.
Some people think dark vs light is opinion, but for some it is not.

- dark mode may present some advantages for some low-vision users
- in users with normal vision, light mode leads to better performance most of the time.
- applications meant for long-form reading (such as book readers, magazines, and even news sites) should offer a dark-mode feature
Depends on if you target a dark or bright ui. If you target a bright environment then you want to work in a bright environment and vice versa, otherwise you bias the work for the wrong environment as you say.
