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.

@naipotato I have astigmatism and dark themes feel more comfortable than the light ones, they are so bright that makes my eyes get tired, maybe I'm weird idk.

What I can say for sure is that dark themes that use straight up black for the background or pure white for the letters feel worse than light theme.

I try to use dark themes for coding and light themes for web browsing to read blogs.

@RiQuY How much is your level of astigmatism? If you don't mind answering, I'd like to know if that has any relation.

@naipotato I think it is -1.25 and -1.50. Probably I don't find dark themes harder to read because I don't have a high value of atigmatism?

Also, I think it's important to mention that I use distance glasses to see my monitor, I don't understand why but 30cm counts as "far" for my eyes. 😕

@RiQuY I understand that in astigmatism the use of glasses is permanent. I have been wearing glasses since I was 4 years old, and they have always been the same, they never made a difference between “near glasses” and “far glasses” ​

I see that your astigmatism is milder than mine, I guess that might affect? I have -4.00 D in CYL.

@naipotato I searched for some metrics and severity of atigmatism and according to this website you have "extreme astigmatism" https://www.visioncenter.org/blog/astigmatism-severity/

Maybe that could be the reason that dark theme is very uncomfortable to you?

Astigmatism Severity Scale: How to Determine Your Level

What is astigmatism? How do you know if you have it? This astigmatism severity scale can help you find out.

@RiQuY Well... it is most likely. -4 CYL, +1 SPH. Astigmatism and hyperopia. Refractive operations are not exactly cheap.
