FIELD: medicine.
SUBSTANCE: invention pertains to physiology, engineering psychology and particularly to such a physiological characteristic of the person as vision acuity. Vision acuity is measured with the help of functional magnetic- resonance tomography when showing test-images with adjusted parametres at a certain distance. Activation of the brain areas caused by the differences between the shown images is registered. Threshold angular parametres of the distinguished test-images are detected and measured; they are correlated with gradation of vision acuity by division of threshold angular parametres by coefficient of the ratio equal to 60.
EFFECT: present method is an objective control method of detection of vision acuity.
