Objective To analyze the results of adolescent vision screening and explore the methods of myopia prevention and control. Methods: The visual acuity screening results of some school students in Licheng District and Lixia District of Jinan city in 2016, 2017, 2018 and 2021 were retrospectively analyzed, and the cases of poor visual acuity were counted. Results: A total of 21,656 students were screened during the four years. The rate of poor vision in all grades increased year by year in the four years except for grade 1 to grade 4 in 2017. There was statistically significant difference between grade 1 and grade 4 in primary school in different screening years (P<0.05).There was no statistical significance between grades and screening years in junior middle school (P>0.05).The visual impairment rate of girls in all grades was higher than that of boys, and there was no significant difference in the visual impairment rate of boys and girls in grade 1 and grade 2 (P > 0.05).There was a significant difference in visual acuity rate between male and female students from grade 3 to grade 9 (P<0.05).However, after entering junior middle school, the difference of poor vision between male and female students gradually narrowed. Conclusions: Affected by the epidemic and other factors, the rate of poor eyesight will increase in 2021, so more effective methods of myopia prevention and control should be actively explored.The rate of poor eyesight of girls is higher than that of boys, so they should be regarded as the key group of myopia prevention and control.
