Sit up straight in front of your keyboard and screen, and keep your
mouse within easy reach
Don't sit in the same position for long periods, get up and move about
periodically
Take a minimum of 5 minutes break every hour from keyboard/screen working
to prevent fatigue and aid concentration
Adjust your screen angle to avoid reflections, and use blinds at windows,
and use a document holder next to the screen if you have to read text
as well
Concentrating on a computer screen for a long time can cause temporary
head pain. Take occasional "eye breaks" by looking out a window or focusing
on some distant object
If your work involves gazing at a computer monitor for long hours, remember
to blink your eyes often to relieve strain
