| Eye strain, neck and shoulder stiffness and low back
pain - these are some symptoms you may experience when working with computers.
Having to keep the same posture over long periods of time is one of the main causes
of physical discomfort. Improperly positioned keyboards or mouse also contribute
to the discomfort. At the early stages of pain, the symptom disappears when a
person stops working with the computer. The potential to develop work-related
musculoskeletal disorders (WMSD)*1, however, increases when computing tasks continue
despite the presence of body aches. These musculoskeletal disorders would persist
until well after work has ended. |

| Staring continuously at the monitor is
another cause of discomfort from computer work. Furthermore, computer work tires
the eyes because the short distance visual task puts much stress on the eyes'
adjustment mechanism. In effect, workers complain of symptoms of eyestrain that
include dry eyes*2, eye irritation, burning sensation in the eyes, and blurring
of vision. Though the symptoms do not progress to permanent vision problems, eye
strain negatively affects productivity at work and more significantly a worker's
attitude towards computing tasks. In addition to the above health problems, devoting
so much time to computer work may lead to mental stress. Social isolation results
from decreased opportunity to talk and interact with co-workers and less chance
to foster social support that helps reduce stress. |

※1 Work-related
Musculoskeletal Disorders (WMSD) are disorders of the muscles, ligaments, tendons,
nerves and bones that result from unfavorable work conditions such as repetitive
movements, awkward posture, poorly designed workstations and long working hours.
The symptoms may range from slight pain to muscle weakness, severe pain and movement
disorder. Any part of the body may be affected such as the hands, neck, and shoulders.
Other terms for WMSD are Repetitive Strain Injury (RSI), Cumulative Trauma Disorder
(CTD) and Occupational Overuse Syndrome (OOS).
※2 Dry
eye is a condition noted when the tear volume is significantly decreased or when
there is qualitative change in the tears that lead to the drying of the surface
of the eyes. |
