Because myopia is becoming the most common eye disorder to cause blindness in young people, Tideman and coauthors evaluate the association between axial length, refractive error, and risk of visual impairment. In a cross-sectional study of data from population-based studies and a case-control study, axial lengths of 26 mm and greater and refractive errors of −6 diopters and less were significantly associated with an increased lifetime risk of visual impairment. Extrapolating these results to regions that have experienced a rise in myopia suggests that it will become a major cause of blindness in the working-age population.
