Aim: The aim of this article is to study the clients’ preferences on corrective lens coating in one of the biggest optical centers in Varna and to present a comparative analysis based on their cost and quality among different manufacturers.
Materials and Methods: The study included 51 participants and their answers to a questionnaire given to them during their visit at the optical center. The questions are directed not only to the client’s personal preferences about corrective lens coating but to their visual health as well.
Results: According to the questionnaire 60.8% of clients use digital devices very often in which case the prolonged staring at the screen without safety glasses leads to headaches, eye dryness and blurry vision. The analysis showed that there are more men (51 %) than women (49%). A large part of the participants have already worn corrective glasses. Seventy-four percent of the group had no preferences about the manufacturer of the lenses.
Conclusion: Our research showed that a large percentage of the participants work with digital devices and are aware that this could lead to visual health problems. Therefore, one of their main requirements was effective blue light protection.
