While working with printed materials, document holders keep them near the user and the monitor. These can be positioned according to the convenience of the user depending on the type of the document and the task performed. Risk factors like awkward postures of the head and neck, fatigue, headaches and eyestrain can be reduced by proper placement of these holders.

Most of your time is spent looking at the monitor. Hence, utmost care should be given in choosing and appropriately placing it in your workstation. Suitable positioning of the monitor would help you reduce exposure to compelling exertions, inept postures, and overhead glare. Possible health issues like extreme exhaustion, eyestrain and related disorders like itching, sty, and power variations of the eye lens, and neck and back pain can be avoided on proper selection of the monitor. The positioning of the monitor should be in concurrence with the other components like the keyboard, desk, and chair.

While using the monitor, ensure the following:

• Ensure that the monitor is in front of you and at least 20 inches away.
• Ensure that the top line of the screen is at or below your eye level.
• Ensure that the monitor is placed perpendicular to the window.

The viewing distance, viewing time, viewing angle, and viewing clarity have to be adjusted to get the best results without affecting your health.
