Factors influencing refractive status distribution and amblyopia in preschool children with low vision.

Hyperopia was dominant in children with low vision.

With an increase in age, the proportion of hyperopic refractive error gradually decreased.

According to multivariate analysis, parental myopia, time spent on close-range eye use, and refractive status were independent risk factors for amblyopia.

Through internal validation, it was found that the prediction model had clinical application value in amblyopia screening.
