Re: ‘Spectacles need and ownership among multiethnic students in rural China’

I wish to congratulate D.-J. Qian et  al. for their original research1 in which they presented a school-based cross-sectional study that described the prevalence and associated factors of spectacles need and ownership among multi-ethnic school students in rural China. They reported factors including demographic characteristics, specta cles usage, and myopia-related lifestyle exposures. As far as I understand from the methods section, questionnaires were filled out by children with the help of their parents.
