Features of the development of visual fatigue in persons with health disorders

Background. The article discusses the qualitative and quantitative features of visual fatigue that persons of different nosological groups may experience. Visual fatigue is one of the factors in deterioration of the psychophysical status of both respondents with psychophysical impairments from the experimental group and relatively healthy individuals from the control group. Aim. The paper aims to study the features of the development of visual fatigue in people with different types of psychophysical disorders and different levels of health. Materials and method. During the study, the following methods were used: observation, self-assessment of the psychophysical status by respondents, and a survey. Results. The results of the study showed that respondents with impaired health and a relatively healthy people had different reasons for the development of visual fatigue and the manifestation of mental responses to intense visual stimuli. Therefore, the emergence and development of visual fatigue can depend both on the mental status of a person and on physical factors that reduce the adaptive capabilities of sensory systems and lead to negative mental responses and health deterioration. Two groups of respondents with a mental and organic basis for visual fatigue were identified. Some respondents showed that they had high levels of visual adaptation and resistance to visual fatigue. They use effective strategies for sensory discharge which can be applied to other groups distinguished by physical and mental symptoms of visual fatigue. Conclusion. The results can be used in the development and application of methods for the psychological and pedagogical support of persons with health problems and are aimed at reducing visual fatigue among participants in inclusive education.
