I venture that this is "highly" depending on personal predilection and
the task at hand. For an exact recommendation, you need to evaluate the
complete environment, the number of times that you are obliged to look
elsewhere, then return to the screen and definitely of the time that you
spend contemplating.

what's harmful is having to stare for hours at too much light coming
from the background...

Acknowledged.

A dark background permits that your eyes "defocus" and your mind can
easily wander, then return to the textual or other content at display
without having to turn away from the screen.

Something only remotely related to the topic: Too many people use dark
backgrounds then forget that a beamer will not project "black light", no
matter how beautiful and ingenious they deem their ideas... ;-)
This is one reason, why I abandoned dark backgrounds for most uses.
Having to convert files back and forth just to allow them to have a dark
background sometimes, is such dumb work... ;->

Cheerio,

Michael.

it would be enough to just reverse colors (like a photo negative) and
keep the printing as if one worked with a bright-background screen.

as offered by pdf viewers in linux and windows...
