To avoid all these problems are advised to follow the following tips as much as possible to maintain our health to avoid eye strain ...
First: the height and the location of the screen
- It is recommended that the height screen fit so that it is at the level of consideration and the height is the ideal that is your view on the screen directly (straight line) to a point located 5 to 7 centimeters below the upper boundary of the screen is also recommended the acquisition screen size of 15 inches at least and advised to put the screen in the appropriate place within the office or room so less reflections of the backlight or windows.

Second: to avoid the pain of arthritis
Affected most of the joints in a way you're sitting in front of a computer is considered hip and knee joint of the most joints affected by the way you're sitting in front of the computer and so it is advisable to follow the proper way to sit down and are sitting so that they form joint angle is also affected by the wrist often in a way your use of the mouse and keyboard and you have to maintain your hands Mstakimtin as much as possible during the printing on the keyboard or use the mouse while maintaining the facility to be closer to your body and be a 90-degree angle between the upper arm and forearm.
Avoid the effect of radiation from the computer:
A radiation produced by computer radiation UV, as well as waves microwave and this radiation small in intensity and quantity, but constant exposure to them may cause future problems and the best way to reduce the effects of the future is to stay away from the screen a distance of not less than 50 centimeters and the use of screen specifications so good that emit radiation less and prefer to use screens liquid crystal instead of the touch technology tube cathode and is known as the tube cathode and a final note in this regard and is that the radiation issue in all directions, and so you have to stay away from the screen from all directions and note in many Internet cafes and corporate offices the user sitting in front of and behind the computer screen directly associate head and, of course, this practice is wrong lead to a doubling of radiation exposure because that user will be exposed to radiation released from its screen and also his screen.
Damage to computer use at night
A recent study showed that the use of a computer or video games at night may deprive the owner during sleep that night.
The reason for this is that the bright light of a computer screen can change the bedtime of the biological and inhibits secretion of the natural hormone melatonin, which is important to the sleep-wake cycle of the people.
And melatonin, a hormone produced by the body to help regulate sleep and waking hours. The researchers say that exposure to light affects the amount of melatonin produced by the body. Which in turn leads to sleep disturbance and especially among the elderly.
The researchers in this study, published in the May / May issue of the journal "Science and Applied Physiology" about the experiences of melatonin in addition to other factors known to affect sleep schedules are biologically such as body temperature, heart rate, which decreased during sleep.
Researchers asked seven people reach the age of one of them 25-year-old waking up between the hours of 8 to 9 am and go to sleep between ten o'clock at night to one in the morning for a week before the start of the experiments.
It then asked the participants in the experiments to do with video games, stunts such as shooting or doing missions boring using computers with screens bright and dim relatively night after the other between the eleventh hour and a half at night and two in the morning and before going to bed to sleep.
The researchers found that the production of the hormone melatonin is greatly influenced by the bright computer screens in addition to the type of task carried out by each participant. Melatonin levels were low after doing exciting tasks in front of a bright screens compared with opaque screens.
At the same time, there was no difference in the level of melatonin while doing tedious tasks.
In spite of the decreased body temperature during the night under all circumstances, the work in front of a bright screen made the user's body temperature is much higher than if the person used a less bright screen.
The researchers say these findings showed that computer users who use it during the night panel bright can be deprived of sleep, because the task of exciting late night can lead to changes in the production of melatonin and body temperature related document date of sleep are biologically
Damages sit at the computer for pregnant women in particular and everyone in general
The impact of computers on the visual system and also on each of the nervous system and skin, as well as their impact on pregnant women is the subject of a government study conducted on 74 people, has computer users compared with sixty people doing office work does not include the use of computers in Egypt, confirmed the results of the study the high proportion of complaints of fatigue visual computer users with the complaint of increased virtual in the degree of myopia and the inability to select colors and in some cases also found that there are cases suffer from a lack of proportion and flash eye study showed that 13.5% of computer users have predicted symptoms of dry eye was also noted an increase in the pain of the neck, shoulders, back, hand and wrist.
The study also indicated that 33.8% of computer users suffer drier Knit in the skin of the face with a red and a sense of burning, and for pregnant women exposed to computer screens and found three cases suffered from abortion and also found a rise in the incidence of respiratory.
The study recommended the need for a computer at home in place to prevent the reflection of light on the screen and remove any surface high near the computer, taking into account the existence of a distance of 50 to 70 cm between the user and the screen and commitment periods short rest for 10 minutes every two hours at least away from the no computers and no secret to everyone that damaged many sit in front of the computer and endless for pregnant and non-pregnant but must be wary of this device and the use of computer addiction affects all parts of the body and must know how to sit in the computer and method of lighting
