Vision Impaired.
Other health problems most frequently reported effect is visually impaired computer users. Impaired vision can cause physical deformities. This happens because when vision is blurred, then the user's computer will alter the body's forward position closer to see objects' that exist in the monitor more clearly. Vision problems caused by computer use, by the American Optometric Association called Computer Vision Syndrome (CVS).

A study published by The Journal of Epidemiology and Community Health took samples basil eye examination 10,000 workers. This work is divided into several groups based on time spent in front of computers at work or at home. Another thing to consider is the length of computer usage in the year. The result is a heavy user computer has a vision disorder, including miopi and glaucoma, so that it can be seen that heavy computer use has a direct relationship with the emergence miopi and glaucoma.

Dr. Masayuki Tatemichi, Toho University School of Medicine, conducts research on workers of different places in Japan which has more than 5,000 workers. He divided the several groups of workers based on how much use the computer, users were divided into mild, moderate, and severe. The result was found in 522 workers suffering from glaucoma.

Nick Astbury said that Japan's population has suffered a high prevalence of myopia, as one of the risk of glaucoma. Because computer users not only in Japan, as noted by David Wright (International Glaucoma Association), that research should also be conducted in other ethnic tested for validity.

Computer as the tool was able to cause occupational disease as well as the use of machinery in industrial activity. Diseases that can result from using this computer, among others, stress, eye and vision disorders and musculoskeletal disorders.

Disturbances above arise because of misuse, such as the location of the screen is too high, the distance the eye with a computer that is too close, not ergs nomisnya keyboard table with the body of the operator, the lighting is wrong, and so forth. Disturbances that arise can be overcome by improving the error above.

With the correct technique of using the occupational disease caused by a computer can be avoided.


Stress
The use of computers can cause stress, such as those found in NIOSH (The National Institute of Occupational Safety and Health). NIOSH found that computer operators have a higher stress level compared to other jobs. This type of stress that can result from using the computer does not have differences with the type of stress that is in life.

INTERFERENCE joints.
RSI.
In addition to the above two things, health problems can be caused by the use of computers in the long term is to fatigue the muscles and tendons, and Repetitive Strain Injury (RSI).

Musculoskeletal disorders caused by the use of computers ranging from weakness of muscles and tendons or neck pain and back up to a cumulative trauma. This cumulative trauma associated with the presence of repetitive movements continuously for a long time known as Repetitive Strain Injury (RSI). The cause of musculoskeletal disorders, among others, inappropriate posture occurs continuously when using the computer, smiles back that does not fit, sit with the same position for long periods and poor ergonomic design.

Repetitive Strain Injury (RSI) occurs because of physical movement which repeatedly caused damage to the tendons, nerves, muscles and other tissues. Increased use of computers with high speed in typing cause injury to the hands, arms and shoulders.

Included in RSI include neck pain, back pain, Carpal Tunnel Syndrome, Tenosynovitis DeQuervains, Thorscic Outlet Syndrome, Shoulder Impingement Syndrome, and Tennis Elbow.
