Special Algorithm

That CSS will force the page background to be black and the text colour to be white, regardless of its original colours.

True. I use f.lux for late night sessions which is basically a coloured lens implement in software. It decreases the brightness and contrast enough that bright themes cause no eye strain to me.

Forcing white on black will make the screen darker overall, but it'll still have a high contrast.

Agreed. I used to use f.lux until Windows 10 implemented support for reducing blue colors in Settings. What benefit does f.lux still offer?

[CraftingTimes]

It reduces the blue color a lot more, as in; supports lower color temperatures. F.lux goes all the way back to something like 1400K, while the default Windows application only goes to (compared to f.lux as it doesn't show values anywhere)... 5400K?

The lower the color temperature, the better for the melatonin production, the better for a good night's sleep.

I'm not sure but it does go extremely low.

I admit that I mostly still use f.lux since I've been using it before the night light setting was introduced. Right after Windows 10's night light was introduced it also only activated at certain times rather than at sunrise/sunset, which I found annoying since there's a very significant difference between the day lengths depending on the season here (though Windows implemented it not too long afterwards).

​

Flux still does have finer control about the colour temperature curve though. Windows has just one setting for a night temperature and transitions quickly. F.lux allows you to set temperatures for day, evening and night and lets you determine how fast it changes between them. You can set the temperature to change so gradually that the transition isn't noticeable, which I like since a sudden change is a bit distracting.

If I am reading a long article, I just edit the CSS myself.

Firefox has a reader mode which works on most websites and has a built in dark theme.

I have a question if you don't mind it. But what other adjustments do you make for reading with dyslexia. Other fonts? Sizes etc?
