Hygienic problems of the digital educational environment and ways to solve them (review)

Abstract

At the current stage, information and communication technologies and digital learning tools are actively used in the education system. The so-called digital educational environment is being formed, which is a set of information systems for ensuring different tasks of the educational process. It allows you to expand the possibilities of building the educational trajectory of students, increase the interest of children and adolescents in the subjects studied by means of showing objects and interactive forms of learning, as well as to develop an educational initiative. However, despite the positive aspects of the digital educational environment, there are also negative factors affecting the health of students. These negative factors lead to deterioration of the nervous, visual, endocrine system, as well as other systems of the developing bodies, the formation of functional diseases and the progression of chronic pathology. For example, it has been established that if there are nospecial preventive measures, the level of functional overstrain of the human body increases, which leads to a decrease in mental performance. Electronic devices used in educational activities are able to optimize the learning process only if they are used rationally in terms of health. In the current digitalization of education, the development of a modern scientifically based practical model of medical and hygienic support of students in a digital educational environment and its testing in general education organizations is of particular importance. It allows to develop the new health-saving technologies, and substantiate criteria and algorithms for assessing the information load of students at the individual, group and population levels. The article discusses the health-related problems of digital schools that require safe learning conditions in order to maintain the health of children and adolescents in a digital educational environment

Prospects for Using Computer Accommodography to Predict Myopia Development in Young Adults

“…The identified high proportion of participants with signs of CVS among young people with preserved normal visual acuity and the absence of refractive errors may be a consequence of the digitalization of the educational process and the educational environment in a broad sense, which has taken place and is still ongoing [ 33 , 34 ]. This is another indication of the growing relevance of using the computer accommodation method allowing the early identification of changes in the main accommodation parameters in schoolchildren and university students, which, if left unattended, can lead to the development of myopic refraction in early years along with gaining education [ 27 , 35 ].…”

Substantiation of the optimum screen brightness parameters of the interactive panel to reduce the risk of general and visual fatigue of schoolchildren

“…impairment, the functioning of the nervous, cardiovascular systems, etc. [1][2][3][4][5][6][7][8][9][10][11][12][13]. The intensity of the educational process is increasing [14].…”

“…The latter has no less negative impact on students' health than the pulsation of general illumination at a workplace because a student is forced to carefully peer at a panel and read information presented on it. The presence of brightness pulsations, as a rule, leads to rapid fatigue of the eyes and parts of the brain responsible for perception and analysis of visual information 1 . You can significantly reduce the panel display pulsation by increasing the brightness of the screen backlight.…”
