Health Safety of Visual Display Units

The proliferation and expanded use of computers in the workplace has raised concern about related health issues. Reports by individuals who use computer monitors or visual display units, referred to as VDUs or VDTs, are filled with complaints of muscular strain and vision problems.

Ocular Discomfort

• According to the American Optometric Association, a nationwide survey of optometrists revealed that about 14 percent of patients suffered from vision issues as a result of VDU use. Symptoms included blurred vision, headaches and eye, neck and shoulder strain. The severity of symptoms often correlates to increased use of VDUs, substandard design of the VDU or the workstation, and undiagnosed vision problems. Ocular discomfort typically subsides once the individual stops using the VDU.

Body and Limb Pains

• Neck, shoulder, back and arm aches associated with the use of VDUs are sometimes known as repetitive strain injuries or upper limb disorders. In addition to good posture, brief rest periods between tasks or alternate work breaks can reduce the stress from repetitive VDU work.

Radiation Danger

• According to tests done by the U.S. Army Environmental Hygiene Agency and the National Institute for Occupational Safety and Health, the radiation emissions from visual display units fall below present standards for all categories of radiation.
