Uncorrected visual acuity (logMAR), cycloplegic spherical equivalent (SE), axial length (AL), average corneal curvature (CC), and subfoveal choroidal thickness (SFCT) were measured at baseline and 6-month intervals for 12 months. Premyopia was defined as -0.50 D \u003C SE ≤ + 0.75 D. A multivariable analysis evaluated predictive factors including age, gender, parental myopia, baseline SE, AL, CC, axial length/corneal radius (AL/CR), and SFCT. Machine learning algorithms were used to predict 1-year myopia onset and myopia shift, along with Shapley Additive exPlanations (SHAP) interpretation. Results: Among 284 participants (88 . 8% retention rate), 141 children (49.3%) developed myopia. The cohort exhibited an annual SE progression of −0.695 ± 0.222 D and AL elongation of 0.356 ± 0.122 mm. The AL/CR increased from 2.986 ± 0.061 to 3.029 ± 0.072 (p \u003C 0.001), while SFCT demonstrated a significant reduction of 21.535 ± 9.731 μm (p \u003C 0.001) . The optimal model achieved an AUC-ROC of 0.963 (95% CI: 0.930–0.997) for myopia onset prediction, with baseline SE emerging as the most significant predictor, followed by parental myopia, SFCT, and age. Meanwhile, our algorithm also achieved clinically acceptable 1-year predictions of SE.  \nConclusion: Premyopic children exhibited accelerated myopic progression. Our machine learning-based predictive models showed promising performance for myopia onset and myopia shift, providing clinically valuable risk stratification for targeted prevention strategies.  \nKEYWORDS  \npremyopia, myopic progression, subfoveal choroidal thickness, machine learning, prediction model  \nFrontiers in Medicine 01 [frontiersin.org](frontiersin.org)  \n1 Introduction  \nMyopia has become a major global public health issue, especially in East Asia. Among Chinese children and adolescents, its prevalence shows an annual increase, increasing from 55.5% in 2010 to 60.1% in 2019, with the peak age of onset dropping from 12 years old in 2010 to 7 years old in 2019 ( 1). An earlier onset of myopia is associated with a higher risk of developing more severe myopia in adulthood.
