Background: Untreated myopia is the leading cause of visual impairment in children, with a huge impact on education, quality of life and socioeconomic status. Objectives: determining prevalence of myopia and some factors related to myopia among secondary school students in Ca Mau city in 2022-2023. Materials and Methods: Design of a cross-sectional descriptive study on 431 secondary school students. Results: the rate of myopia accounted for 29.2%. There is a statistical significance of the time watching TV, phone (p=0.021) in the group of myopia and non-myopia, the average difference is 13.1 minutes. Students who go out to play at break time in the non-myopia group accounted for a higher rate (74.7%) than the myopic group (25.3%) with p=0.006. When they have free time at home, students who often go outdoors to play in the non-myopia group are 1.76 times higher than the myopic group (p=0.013). Students in urban areas have a higher rate of myopia (39.4%) than in rural areas (19.3%). All the above differences are statistically significant (with p<0.05). Conclusions: More communication training should be given to students about myopia and sports activities to limit children's early myopia.
