Computer Ergonomics FAQ’s

Q. What is the best position for the monitor at my workstation?

Many make the mistake of putting the monitor, the keyboard, or both off to one side on a desk. If you perform more than a few minutes of keyboarding a day, the keyboard and monitor should be placed directly in front of your normal sitting position. The screen should be 18-30 inches from your eyes, or about an arm's length.
Try to get monitors with faster screen refresh rates of at least 60-70Hz. The contrast and brightness of the monitors should be adjusted according to the surrounding lighting conditions. Reduce the onscreen glare by adjusting the position of the monitor.

Q. Is there an optimum height for my monitor and mouse?
Yes. The top of the monitor should be at around 12 degrees below eye level because the eyes are at their most comfortable position. Desktops or laptops monitor centers should never be above the eye level and also too below. This posture also makes it easiest to balance your head above your shoulders with the least muscular effort.

Q. How often should I change positions and take breaks during keyboarding?
You should change your sitting position at least every 15 minutes. Active breaks should be taken at least every 20 minutes especially for those who perform more than 2 or 3 hours of keyboarding a day. Microbreaks should occur more often. Try and blink more while working on computers.

Q. How can I improve my body posture to lessen the burden on my eyes and body?
You sit comfortably in front of computers on a chair with a support for your lower back. Placing your elbows on the arm rest of the chair reduces muscles strain in arms. You should always place your feet parallel to the ground preferably on a foot rest. Try not to lean on the table, keep your back straight.

Q. What are some of the best exercises for keyboarding microbreaks while seated?
Following are a few basic exercises:
  • "Shoulder Blade Squeeze" is performed by raising your forearms and pointing your hands to the ceiling. Push your arms back, squeezing your shoulder blades together. Hold for at least 5 seconds and repeat 3 times.
  • "Eye Palming" is performed by placing your elbows on your desk, cup your hands, close your eyes, and place your eyelids gently down onto your palms. Hold this position for 1 minute while breathing deeply and slowly. Then uncover your eyes slowly.
  • The "Arm and Shoulder Shake"--drop your hands to your sides then shake your relaxed hands, arms, and shoulders gently for at least 5 seconds and repeat 3 times.
  • "Spanning"--place you arms straight in front of you and spread your fingers as far as possible for at least 5 seconds and repeat 5 times. This exercise was made famous by career pianists. With the arms extended in front of you, spanning can be combined with a "Forearm Extensor Stretch", by turning the hands so that their backs touch then, turning them so that the palms face the ceiling ("Forearm Flexor Stretch").

These are only a few exercises; however the best form of exercise for eye relaxation is the one that is suggested according to Individual eye relaxation needs as prescribed by a Vision Therapy specialist.

  • Use large size font: The font size should be three times larger than the normal font size you could read on your screen.
