Sophistication of computer technology, especially the very rapid development, other than that this great technology that was almost possessed by all people, it is because that computer technology has many functions, so that people who have felt was in the activity or daily activities.
Computer users at this time also varied ranging from kindergarten children to adults, because of the ease in operation then it is not possible anymore if the child can also make use of TK. If you see this writer feels there is a sense of pride and there are also feelings of worry, proud that kindergarten children can now use a computer with good compared with the author as they age, however the author is also concerned about their health, because the use of computers when in the hands of children mostly for playing computer games so that adverse effects will soon be upon them.
The author found several articles from the internet which explains some facts about the negative effects on the health of the body such as the computer is:
Radiation Monitor
Eyes are organs of the body most prone to illness due to work, because too often focus eyeballs to the screen. Display screens are too bright hot colors like red, yellow, purple, orange will be more accelerated fatigue in the eye. Apart from that, the reflection of light (glare) on the display monitor that comes from other sources such as windows, lighting, etc., will increase the burden of the eye. Workspace lighting also affects the burden of the eye. (1.3) Use the screen that are not ergonomically may cause a complaint to the eye. Based on this research, 77% of users will experience the monitor screen at eye complaints, ranging from feeling sore and painful on the eyes, red eyes, watery eyes, eye irritation to the eyes of even the possibility of cataracts.
When the computer operator to use soft contact lens (lens of the eye), eye fatigue will be felt sooner, because the eyes are in a state of focus to the screen so that the ball will rarely blinks his eyes rapidly became dry and this causes friction between the lens and eyelids. Space-cooled (AC) would be more aggravating friction, because the air conditioned room air is dry so the tears would come to yawn. According to the research by the author, for a computer operator who works eight hours per day continuously, apparently out of the computer radiation (especially X-rays) is very low, approximately 0.01739 m Rem per year. This price is much lower than the radiation coming from cosmic rays and radiation from the earth (terresterial radiation) ranging 145 m Rem per year. While the radiation dose rate allowed for the general public is 500 m Rem per year
Lately, many sold glass monitor screen filter to filter the radiation that was promoted as an exit from komputer.kaca filters on the market are better suited as a filter glare (glare) from the light of computer screens, not as a radiation filter.
Nerve disturbance
Printers who use the system relatively lebihrendah buble jet noise compared to dot matrix printer system. Currently the most low-noise printer is a laser printer system. High noise can affect the human nervous and this can result in fatigue and soreness. The noise limits are allowed to work for less than eight hours per day is 80 dB. Whereas the ideal working space is to the noise around 40-50 dB. If there is work in the space of the refrigeration (AC), then the noise will grow apart from the sound of the printer.
Repetitive Strain Injury (RSI)
RSI is a term that refers to several variations of skeletal muscle complaints (musculoskeletal). This complaint concerns known to the muscle tendon pain. RSI covers the upper arm disorders associated with the work (the Work-Related Upper Limb Disorders) and overuse injuries associated with working (Occupational Overuse Injuries).
These complaints mainly suffered by the workers with a static sitting position when using a computer or using repetitive hand movements (repetitive) every day, a static workload (such as holding a mouse), allowing the arm bends, and the like in a long time. It will get worse if the workplace is not ergonomically designed, for example the position of the keyboard and the monitor that is too high or too low, the chair does not support the body to sit upright, and so forth.
This will get worse if the working environment plus a less mobile, less rest, containing high stress with deadlines and other regular reporting as well. Especially if you are a smoker, suffering from obesity (obesity), muscle weakness, have a hand that feels cold and lack of exercise.
Early symptoms of RSI can appear in various places from the base of the arm to the tip of the hand. Symptoms of a warning sign regarding:
• Difficulty opening and closing hands
• Muscle cramp hand (for example up to difficulties buttoning shirts)
• Difficulty using hands (to turn the pages of books, play button,)
• Wake up with pain in the wrist or numbness in hands, especially in the early morning
• cold hands
• Hand shaking (tremor)
• The hand feels awkward, vibrate, or even numb.
Judging from the negative effects on the computer it's good as a parent even adults themselves need to consider how to use a good computer, using an appropriate computer technology and will reduce the risk as described above. Hopefully this article the author may have benefits for us all. amen
