Visual acuity, accommodation, fusion reserves, capacity for visual work, pulse rate, body temperature and vegetative nervous system condition (according to data of vegetative tests) were controlled for all the children every 2 hours during 3 days running in order circadian biorhythms to be revealed. Daily fluctuations of the functions were revealed both for healthy children and for ametropes. Mean quantity of fluctuation's period for healthy children was 24,04 hours. Shortening of biorhythm's period and decreasing of their amplitude were noted for children 5-7 years old in comparison to schoolchildren. It is possible that this fact testifies about next: forming of visual system's biorhythms in this age is not completed. Enough strong correlation between circadian biorhythms of some visual f unctions and vegetative nervous system was revealed in healthy children. In cases of ametropies there were changes of biorhythmic curve: shortening of period, increasing or decreasing of amplitude the fluctuation, disorders of correlative ties in different degree. Persons with myopia had the highest degree of the changes. Results of the investigations were taken into account for choice of time and treatment's tactics as regards to children with visual function disorders.
