    Abstract:

    AIM: To review existing data for the prevalence of corrected, uncorrected, and inadequately corrected refractive errors and spectacle wear in Hungary. METHODS: Data from two nationwide cross-sectional studies were analysed. The Rapid Assessment of Avoidable Blindness study collected population-based representative national data on the prevalence of visual impairment due to uncorrected refractive errors and spectacle coverage in 3523 people aged ≥50y (Group I). The Comprehensive Health Test Program of Hungary provided data on the use of spectacles in 80 290 people aged ≥18y (Group II). RESULTS: In Group I, almost half of the survey population showed refractive errors for distant vision, about 10% of which were uncorrected (3.2% of all male participants and 5.0% of females). The distance spectacle coverage was 90.7% (91.9% in males; 90.2% in females). The proportion of inadequate distance spectacles was found to be 33.1%. Uncorrected presbyopia was found in 15.7% of participants. In all age groups (Group II), 65.4% of females and 56.0% of males used distance spectacles, and approximately 28.9% of these spectacles were found to be inappropriate for dioptric power (with 0.5 dioptres or more). The prevalence of inaccurate distance spectacles was significantly higher in older age groups (71y and above) in both sexes. CONCLUSION: According to this population-based data, uncorrected refractive errors are not rare in Hungary. Despite recent national initiatives, further steps are required to reduce uncorrected refractive errors and associated negative effects on vision, such as avoidable visual impairment.
