Multi-center Ocular Biological Parameters Study

①Relevant domestic studies on the biological characteristics of the eye are mainly limited to a certain city and region. Most of the studies that represent the biological characteristics of the general population in China and the differences in biological parameters at home and abroad are in the research process, or Semi-finished products.

②The investigators found in clinical observation that the eyeball biological data of the Chinese population may not be consistent with the foreign population.

③ This study is the first study of human eye biological parameters based on different regions of large-scale populations in China, which is of great significance for understanding the human eye structure in different regions of China.
