You should make your work-life as comfortable as you can - you can make your space more ergonomics by starting with a Herman Miller chair at Beverly Hills Chairs.
1) You should adjust the monitor height so that the top of the screen is below eye level. Your eyes should look downward when viewing the screen.
2) Position the monitor no closer than 18 inches from your eyes. A good rule to keep in mind is an arm's length distance. The larger your screen, the more distance you will need.
3) Adjust the screen position to eliminate any possible glare from windows and lights.
4) If lighting conditions permit, tilt the monitor backs 10? : this maintains the same distance between your eyes and the screen as you scan it from top to bottom.
5) The center of the keyboard should be level with the height of your elbow.
6) You should also tilt the keyboard back 10? so that your wrists remain flat.
