Summary

This study aims to create standard charts for eye length in healthy Chinese children and teens aged 3 to 18. Researchers will measure the eyes of 30,000 participants once a year for three years to see how eyes grow and how nearsightedness develops. The study does not test any treatment—it only observes and collects data.
