4 Adjusting your monitor Scan your head, neck and torso for comfort There is no one monitor placement that can keep all body parts happy at all times. Throughout the day, let the comfort of your eyes, neck, shoulders, and back help you determine what to move and when. Placement, zoom, and lighting are all important factors that affect your comfort and productivity. For example, if your eyes are getting dry, you may want to lower the monitor for a while and blink regularly. If you are starting to experience eyestrain, try increasing the percentage of zoom to enlarge the size of objects on the screen. You also may need to draw the monitor closer, eliminate light sources that cause glare, and take frequent eye breaks. If you are looking downward and start to feel neck discomfort, you may want to raise the monitor. Your head should rest comfortably over your shoulders and your back should be fully supported by the chair. RIGHT Keep your head balanced comfortably over your shoulders with your back fully supported by your chair. Follow these guidelines for adjusting the monitor: ● Place the monitor in a location where glare and bright reflections are eliminated. Try to avoid bright light sources in your field of vision. ● Place the monitor directly in front of you to avoid twisting your neck and torso. ● To avoid craning your neck forward to view text that is too small, experiment with adjusting the percentage of zoom to 125 percent or higher. For computer use, you may find character height of three millimeters to four millimeters most productive for reading. Scan your head, neck and torso for comfort 9
