Some people, including me, have what's commonly called ‘astigmatic halation’ — although it's often not due to simple astigmatism, but rather ‘higher order abberrations’‡ which aren't correctable by glasses.

For this case, dark text on a light background is much better than light on dark. Dark on light, the light halation blends more or less evenly over the dark letter stems, resulting is slightly lower overall contrast but sharp lines. Light on dark, it's Las Vegas in the rain.

I envy individuals who organize their digital information in this way. Yes, I can practice discipline. Yes, it is possible. And it has always been (and continues to be) an uphill battle to keep my information tidy in this way, when my is scattered at best.
