Don't. Ever. Publish. Stuff. That. ONLY. Supports. Dark. Mode.

I mean, I know a LOT of people love dark mode, and given the benefits that darkening interfaces provides... I get it.

But there are some people (like me) who may be visually impaired. Astigmatism, for example, can make reading text that is white on dark a real PITA. An effect known as "halation" occurs, where each letter behaves as if it were a flashlight, gaining its own halo of light and making all text read more blurry than normal.

No matter how good your glasses are, astigmatism still causes you to see a little blurry—it's something you get used to. But this damn effect makes all the text read as if you don't have your glasses on, or even worse, leading to much more tired eyes or even pain.

For everyone's sake, if you really care about accessibility, respect user preferences. If you want a dark interface by default, offer a light version if the user specifies it (in web design, this would be
prefers-color-scheme: light). The same goes for light interfaces.
Dark Mode Isn’t ‘Easier on the Eyes’ for Everybody

Apple’s new dark mode for iOS 13 can save battery life, but it won’t save everyone's eyes from screen strain.

VICE

@naipotato I don't know if one of their sources ever pointed this out, but paper has long been black text on white...for, like, every book in existence.

How many book reviews have gone "The book's contents are fine, but reading black text on white is an eyesore!"?

@AT1ST Well, it's not the same in that case. Books don't have their own light source, screens do.

@naipotato Well that is kind of the point; it is pretty likely that it isn't that dark mode is better for one's eyes, it's that it's the fact that we're staring into miniature suns powered by lightning.

The solar eclipse could be considered the "Dark Mode" of the sun - doesn't mean we should really be staring at it, "Dark Mode" or "Light Mode".

@AT1ST Indeed. But the truth is that this problem is solved quite well with e-ink displays. Hopefully they can evolve further.
