In a few short years computers have invaded our workplaces, homes and laps. The dream of the original computer pioneers of a computer in every home has become a reality - and so has computer stress: eye strain, wrist 
pain and the other discomforts that occur from long periods of computing. How can we avoid such stress?
To relieve eye stress, keep your eyes at least 18"-24" from the screen and rest them periodically - look out into the distance or out a window. If you face a wall, place a mirror near your computer and focus on a distant object through it. Also breathe deeply because shallow breathing creates tension and fatigue. Remember to get up and walk around, stretch and relax.
