Objective  To investigate and analyze the status of poor vision in adolescents and the related influencing factors.

Methods  A retrospective analysis was conducted to select 1 256 adolescents who received visual acuity examination in Eye and Optometry Center of Wenzhou Medical University from July 2021 to October 2022 as the research subjects. The patients were grouped according to whether they had detected impaired visual acuity. 527 adolescents without impaired visual acuity were set as the control group, and 729 adolescents with impaired visual acuity were set as the observation group. The status of poor visual acuity among adolescents was analyzed, and the relevant influencing factors of poor visual acuity among adolescents were summarized by univariate analysis and Logistic regression analysis.

Results  In 1 256 cases of adolescents, 729 cases of poor vision were detected, accounting for 58.04%. Among them, 186 cases (14.81%) had mild impaired vision, 213 cases (16.96%) had moderate impaired vision and 330 patients (26.27%) had severe impaired vision. The score of quality of life in observation group was higher than that in control group, and the score of visual care behavior was lower than that in control group (P<0.05). Univariate analysis and Logistic multivariate regression analysis showed that gender, residence, heredity, reading distance, reading and writing posture, time spent online, outdoor activities, diet, eye exercises and sleep time were not only related but also independent influencing factors of poor vision in adolescents (P<0.05).  Conclusion  The current situation of poor vision among adolescents is not optimistic, and targeted measures need to be taken in time to improve their visual health and quality of life.
