That's so interesting! I find that the white text on a black background produces a weird, edgy blur around the edges that feels like anti-aliasing from gaming... Have you been diagnosed?

The name for this is ‘astigmatic halation’.
The same blur is present for me on text on a white background...it just wasn't as apparent to me as, say, blue glowing signs at night or a microwave clock. But wearing glasses, the text is noticeably crisper and less "bold" looking. Which results in not having eye strain. The halation is still there, but it's just less obvious what's going on.
I just assumed everyone saw the same thing at night for a long time...and would never have even guessed something was off about regular black-on-white text without having an optometrist clue me in.
