It is important to consider the placement of your computer monitor. Improper viewing distances may contribute to visual fatigue or eye strain. If the monitor is placed too high or too low, your neck muscles will have to work harder to hold your head in viewing position which may result in fatigue and discomfort over time.
- The viewing distance between your eyes and the computer monitor should be in the range of 40 cm to 74 cm, or approximately one arm’s length away.
- Center the computer monitor directly in front of you so you do not have to turn your head to one side or the other to view the screen.
- If working with two monitors, it is usually recommended that the monitors be equally centered in front of you. If one of the two monitors is used only occasionally, it may be more comfortable to place the frequently used monitor directly in front of you, with the other monitor immediately to the side of the first. Both monitors should be placed at the same viewing distance.
- Adjust the height of the monitor so that you can look at the monitor with your head and neck in an upright and relaxed position.
- When looking at the computer monitor, the top line of text should be at approximately eye level.
- If you wear bifocals/trifocals and are viewing the monitor through the bottom half of your glasses, you will need to position the monitor at a lower height than you otherwise would; avoid tilting your neck upwards to view through the bottom section of your glasses.
- If your monitor is not height adjustable, an adjustable monitor stand can be used to support the monitor at the desired height.
In addition to proper monitor position and height, the monitor should also be adjusted to comfortable levels of brightness, contrast, and font.
