The hygienic assessment of the mode of using mobile electronic devices (ED) was carried out to develop preventive activities aimed at education of medical students. A total of 518 medical students were surveyed. The survey was created in Google Forms. The obtained data were processed with Statistica 13 PL. The study was conducted in accordance with the principles of biomedical ethics and did not expose the participants to any danger. Data on a habitual mode of using mobile electronic devices by medical students during their traditional educational process were obtained through the survey: half of them never did eye gymnastics, over 75.0% reported holding their mobile ED very close to the eyes, 75.0% of those surveyed used mobile ED in the lack of light. While assessing the mode of ED use by medical students, it was established that the visual organ sustained the largest burden. Preventive activities are necessary to avoid negative consequences and produce useful skills of using ED during education of future doctors at a university.
