This observation is not to diminish the conclusion of the study, but rather to strengthen it. I) Even if evidence supports the increasing prevalence and the growing burden of disease potentially related to myopia, it is not clear if datasets collected in the previous years were standardized and/or are comparable to the newly collected data, both in terms of demographics as well as of sample size. However, epidemiological results and pathogenetic mechanisms may benefit from additional considerations and information.
