World Children`s Day is celebrated worldwide on November 20
Vision gives people 90% of information from the outside world. Good vision is necessary for any human activity: education, recreation, daily life. It is important to understand how to properly protect and preserve your vision.
It has already become an indisputable fact that unregulated visual loads in schoolchildren lead to decrease in vision. According to the WHO, in developed countries, 20% of preschool children and every fourth schoolchildren have vision problems. Therefore, prevention of decrease in visual functions in children is of particular relevance in the computerization age.
It is necessary to start the prevention of decrease in visual functions in children from the birth . This process should be complex, including not only medical aspects, but also social ones. Ophthalmologists, pediatricians, parents and teachers should be involved in the process of preserving the vision of children.
It should be noted that the age , at which a child enters school , coincides with the period of functional instability of the organ of vision. Moreover, already 4 - 5% of children have vision problems and wear glasses before the education period. At the same time, the educational process is associated with a significant increase in the load on the eyes: the amount of visual load among elementary school children averages 5-7 hours a day (30-42 hours a week), senior and senior high schoolchildren - 8-10 hours a day (48 - 60 hours a week). If a child is rarely in the fresh air, inactive, weakened by frequent illnesses, then he is at an increased risk of developing visual disorders.
The most common forms of visual disorders at school age are: accommodation spasm, myopia, hyperopia and astigmatism.
The lack of movements inevitably affects functional properties of the visual analyzer - our eyes. On the other hand, excessive information load on the eyes and brain leads to serious disorders and diseases. In developed countries, every fourth person is myopic. This issue has become especially acute in recent years due to the detrimental effect of displays and computers on vision.
At school age, systematic physical exercises are recommended . These exercises aimed not only to develop physical qualities and ensur e motor actions, but also to develop culture of movements and to prevent diseases. Physical education and sport provide an improvement in the activity of all organs and systems, stimulate metabolic processes in the body, which have positive effect on vision.
