What is the correct way to face a computer screen?

Correct positioning of the body at a computer, also termed ergonomics, is essential to preventing physical medical conditions such as carpal tunnel syndrome and back pain. You should sit so that your eyes are 18 to 24 inches (45 to 61 centimeters) from the screen, and at a height so that they are six to eight inches (15 to 20 centimeters) above the center of the screen. Your hands should be level with or slightly below the arms.

Correct posture is also necessary. You should sit upright, keeping the spine straight. Sit all the way back in the chair with the knees level with or below the thighs. Both feet should be on the floor. The arms may rest on the desk or chair arms, but make sure you do not slouch. If you need to bend or lean forward, do so from the waist.
