Myopia and astigmatism are common visual abnormalities in human populations worldwide. The studies in Bulgaria concerning the population structure in context of these defects and thair relations with sex, age, etc. metrics are limited. Reasonably the present study aims to analyze peculiarities in the manifestation of myopia and astigmatism by characterizing the sex, age and AB0 blood group structure of a reproductive population in southern Bulgaria. The study includes 817 individuals of both sexes, aged between 18 and 59 years. They voluntarily have filled out a questionnaire, giving diseases information (myopia and astigmatism), after they had been diagnosed by a physician. AB0-blood group affiliation has been determined in laboratory conditions by a routine technique. Based on the obtained results, it is concluded that female sex and age over 44 years are risk factors for manifestation of the studied refractive abnormalities, and blood groups A and 0 hide a greater risk for their joint manifestation.
