My opthalmologist spent some time talking at a "lunchtime learning"
seminar about exactly this subject.  The net product of this endeavour
will be to gain for yourself a case of "accountant's eyes".  This is what
is now known as "loss of accomodation".  In other words, you DIMINISH your
ability to "accomodate" changes in focal distances.  His recommendation
was that workers at VDT devices look into the distance every once in a
while (something at a significantly different focal distance from the
tube).  This would reduce the impact of your VDT use as far as
accomodation goes.  What you're setting yourself up for is a tremendous
dose of trouble.
