Studies have shown that the excessive contrast of black text on white overstimulates the eyes, creating more eyestrain than dark grey (#444).
Here’s a study showing how the overstimulation from black text on white background can cause myopia through choroidal thickening (and the reverse, with white text on black background causing choroidal thinning.) https://www.nature.com/articles/s41598-018-28904-x
The problem with that is that not all displays show the same colours and contrasts, so what looks like one shade on monitor A can look totally different on monitor B. Combine that with the massive number of sites that just have any old gray, as opposed to a specifically recognised dark gray, and you frequently end up with text appearing is light or mid gray.
When this happens, (which you notice a lot on certain monitors) the eye strain is faaaaar worse than a nice thin black text. I find myself pressing CTRL-A at times to highlight everything on the page for a little more contrast, because the standard text is so unreadable.
If the shade is really that different, then the problem is a poorly calibrated screen, and black text on white is also going to look “totally different”.
You don’t always have control of calibration settings when you’re on someone else’s monitor, but at lest black always looks black and is still readable without selecting text to change it.
Also, as I said, not everyone uses the same shade of gray when building a web page/style/theme. In fact, far from it. Black however, is always black, one shade, 000000.
