Dry eye syndrome is one of the common problems of modern ophthalmology. An ophthalmologist can make an individualized selection of therapy according to the results of the violation of the quantitative and qualitative ratio of the tear film layers.

The aim of the work was to determine the dependence of the quantitative characteristics of the tear film condition of both eyes in adults.

A retrospective analysis of the results of the tear film diagnosis of 783 adult patients has been used during the research. The thickness of the lipid layer, the height of the tear meniscus, the non-invasive tear break-up time, and infrared meibography data have been studied. Data have been compared separately for left and right eyes.

The norm of all indicators of both eyes have not been noted in any of the examined patients. The norm of all indicators of one eye have been noted in 29 patients.

The result of the analysis of the received data has shown that there are no recommendations regarding the specifics of the use of substitute therapy in the case of existing differences in indicators and symptoms for the left and right eye.

A difference in the non-invasive tear break-up time score between the right and left eye for patients of both sexes was revealed. We consider it appropriate to review the norms in the software, to collect a database separately for the right and left eye.

There is a need to focus the attention of patients on the features of the use of the drugs used for dry eye syndrome.

Key words: dry eye syndrome, tear film.
