Aim: The aim of this article is to present a comparative analysis of the advantages and disadvantages of multifocal glasses by different manufacturers and to assess optical technology development.

Materials and Methods: The study included 5400 participants. Six percent of them ordered multifocal glasses and therefore were divided into twelve groups based on their gender, refractive error and type of multifocal optical product, which they have used in the past and/or ordered now.

Results: The analysis showed that more men (60 %) preferred multifocal glasses than women (40%). Based on the refractive error, there were more myopias (80%), than hypermetropias (20%). There was no difference between participant preferences based on multifocal lens manufacturers – Asian or European (50%).

Conclusion: To achieve desired optical sufficiency it is very important what kind of optical product will be chosen. If the glasses frame is properly selected and comfortable, the client will have enough panoramic view because of it, and the visual satisfaction will be maximal. Optical specialists and their professional qualities are crucial for the final product to present 100 percent of its capacity.
