Re: Letter to the Editor of Public Health in response to ‘Spectacles need and ownership among multiethnic students in rural China’

We thank the reader for this valuable comment.1 In our study,2 children filled out the questionnaire with the help of their parents because information on parental myopia, parental education level, and other information might be beyond the understanding of children of young age. Although we agree with the reader that potential biases might have taken place, this method has been widely used in epidemiologic studies in children. In the article, we have recognized and mentioned the possible information biases in the discussion section.
