Purpose. To study the effectiveness and features of the mechanism of action of the device «Visotronic Mini» in correcting the adaptive resource of the visual system in students. Material and methods. The study involved 30 students (60 eyes) with visual asthenopia, whose average age was 21.6 years. The ophthalmological examination included a questionnaire, visometry, and determination of subjective refraction and binocular stability of visual perception (SVP) to hypermetropic retinal defocus (HRD). Each student underwent a course of optical kinesiotherapy using the device «Visotronic Mini». Results. After the course of treatment, SVP to GRD increased on average from 380.3 to 479.3% after avergent eye movements, and increased on average from 399 to 503% after divergent eye movements (p<0.001). Moreover, as the need for accommodation increases with the increase of HRD, a regulatory redistribution of muscle tone is noted in the diverging muscles, up to a change in the stress vector, that leads to a temporary change in the geometry of the eyeball. Conclusion.The use of the device «Visotronic Mini» significantly increases the performance of the ciliary and oculomotor muscles, and also improves the elastic properties of the sclera and the hemodynamics of the eyeball, i.e. factors that form the basis of the adaptive resource of the visual system Key words: correction of adaptive resource, extraocular divergence accommodation, structural remodeling of the sclera
