Surprisingly, I really haven't. I've been computing for about 10 years, and
from late 1989 to mid 1992 worked full time as a programmer [with a horrid
amber 12" screen], in addition to spending about 8 hours a day on the net
from home. I am also an avid reader, and spend a lot of time engaged in
_those_ activities.
I read somewhere that as long as the eyes are frequently refocused, they will
not become "stuck" in up-close or far-off mode. In reaction to this, I have
always placed my CRT adjacent to a window, so that I could look at a distant
object whenever I pleased.
As my family has a history of poor sight [my father, mother, and sister were
all wearing glasses by the time they reached adulthood], I suspect eventually
I will end up running into problems. I don't think computers will be to blame
for them, though.
I currently use my computer for at least 8 hours on the average day, and
aside from the looking-out-the-window trick, I can recommend using a VGA
monitor, as large as possible, with dark letters on a light background. In
theory, brown letters on white strain your eyes the least. I am currently
using a nice GUI on a VGA/greyscale monitor, so I have dark grey letters on
a white background, which is also nice. My screen is only 14" diagonally,
so the letters aren't too big, but I can vary their size, and they're very
well-defined.
