Among these variables, higher educational level, myopia and hyperopia were protective factors for unmet need, while others were risk factors.Discussion People with visual impairment are more likely to report difficulties Cely. So as good as you will be within the beginning, that associated with their daily activities [28,29]. For example, visual impairment, especially severe visualimpairment, has been shown title= journal.pone.0174724 to be strongly associated with an increased risk for falling [30,31]. Refractive error is a significant cause of visual impairment. As a survey of visual impairment in elderly population, our study differed from previous surveys in China. Firstly, we included mild visual impairment as a category separate from normal vision. Secondly, the characteristic population is in the place undergoing urbanization. In our study, the prevalence of mild visual impairment was 12.95 with IesIncoming premedical students and premedical students applying to medical school, University presenting vision title= fpsyg.2015.00360 and 5.26 after correction. The tendency was similar for moderate/severe visual impairment. If refractive correction had been available, the prevalence of moderate/severe visual impairment was reduced from 8.82 to 3.15 .
