Just a user preference to prevent/lessen presbyopia from watching
dark-on-white.
o Light causes the iris to close (that's the reason for sunglasses) and
for long time, that muscles can stop working well and the retina start
receiving much more light than it should. Needless to say retina can
burn.
o For people with presbyopia and similar, It's easier to read on white
backgrounds mainly because the "iris" closes for the light and that
fact makes the blur disappear. Similar to the cameras.
