Introduction. According to ophthalmologists, the number of patients with signs of asthenia and asthenopia has increased substantially over the past few years. It is a known fact that good nutrition, adequate intake of vitamins and minerals with diet, compliance with work-rest regime is a necessary condition for the prevention and elimination of clinical presentations of these pathologies.Aim. To assess the results of the use of biologically active food additives Doppelherz® Kinder Omega-3 for children from 7 years old and Doppelgerz® Kinder multivitamins for children in paediatric population with signs of asthenia and asthenopia.Materials and methods. A total of 90 children aged 7-12 years with signs of reactive asthenia and asthenopia were included in the study. Patients in group 1 received the biologically active food additive Doppelherz® Kinder Omega-3 for children from 7 years old; patients in group 2 – Doppelgerz® Kinder multivitamins for children; patients in group 3 – did not receive any biologically active food additives or vitamins.Results. The CISS questionnaire showed a reduction in the severity of signs of asthenopia in group 1, less pronounced reduction of signs in group 2, and insignificant reduction in group 3. The Swanson scale showed a decrease in the degree of inattention in group 1, a decrease in the degree of inattention and impulsivity in group 2. I.K. Shats questionnaire showed that asthenia decreased from severe to moderate in group 1, and from severe to a fatigue reaction in group 2. In all groups that complied with the general recommendations, an increase in the relative accommodation reserve was observed. Evidence from pupillography indicates decreased accommodation tension, which was more pronounced in group 2 as compared with group 1, and insignificant in group 3. The Norn test and the tear meniscus height values confirmed an improvement in the tear film status, which was more pronounced in group 1 than in group 2.Discussion. There are three main directions of the treatment strategy for asthenia: etiopathogenetic, nonspecific and symptomatic therapy. Targeted addition of vitamin and mineral complexes to a child’s diet is a reasonable and integral part of the pathogenetic treatment of asthenia and asthenopia.Conclusion. A decrease in signs of asthenopia, improvement of the tear film state, reduction in signs of inattention due to increased concentration, and improvement of memory was observed in the group of patients who used the biologically active food additives with omega-3 for children from 7 years old, as compared to the control group. A decrease in signs of asthenia, and improvement of the tear film state was observed in the group of patients who used multivitamins for children — chew strips with raspberry flavour.
