I am a bookkeeper and work with the computer and printouts all day. I have double vision when looking.One thing that has helped is I got a desk that resembles a drafting table.It brings the paperwork up to a better level for me and I don’t have to look down so much. Another thing I did is turn off those flourescent lights!I now have lamps all over the place but it has really made a difference.Hope this helps,good luck.
