Objective: To investigate the relationship between IPD of children and adolescents in Qingdao and Hohhot, and to study the law of pupillary distance growth in children and adolescents. Methods: A total of 4 971 children from 5 to 17 years old in Qingdao and Hohhot were surveyed by cross section. The pupil distance was measured by vernier caliper and the results were analyzed. Results: The pupillary distance of children aged 5-17 years in Qingdao increased from 52.07mm to 60.19mm, the pupillary distance of children and adolescents in Hohhot increased from 50.77mm to 5 9.39mm, and the pupillary distances in both regions were (P <0.01). The average pupillary distance in Qingdao was 5 7.03 mm, which was greater than 56.28 mm (P <0.01) in Hohhot. Conclusion: The pupillary distance of children and adolescents in the two regions has experienced growth and development at 6-9 and 10-15 years old. The male pupil is 16 years old and the female pupil is 14 years old. The pupillary distance has reached the adult level
