Dear all,
I recently had an inquiry from a computer firm where some of the staff
apparently prefer to work in rooms that are so dark they can only just see
the keys on the keyboard. I was asked if this could cause eyestrain. I did a
quick search and found no evidence one way or the other. I suspect that
slowness of dark accomodation coupled with the need to see other things as
well as the screen might be the reason for any eyestrain. I remember half a
century ago (in the fifties) when television was still a novelty in England
(and I was still a child) I was told not to watch the TV in a dark room as
it "draw my eyes", that is to say, tire them needlessly. Is there a simple
answer to this question?
Regards, David McFarlane.
