WebNov 5, 2013 · Risk factors for refractive errors have been extensively investigated in previous population based studies [20-23]. Among these, education is a strong and consistent risk factor for myopia [12,23-25]. WebRefraction measurements were converted into spherical equivalent refraction (SER), which was calculated as the spherical value plus half of the astigmatism value. Medium to marked hyperopia was defined as >+2.0 dioptres (D), and mild hyperopia was defined as >+0.50 D and ≤+2.0 D, in one or both eyes if neither eye was myopic.
