Abstract
Purpose: We sought to evaluate visual performance and satisfaction with ready-made spectacles (RMS) in Chinese school-aged children with uncorrected refractive error. Design: Randomized, double-blind, clinical trial. Participants: Junior high school students from urban Guangzhou, China, aged approximately 12 to 15 years with ≥1 diopter (D) of uncorrected spherical equivalent (SE) refractive error. Students were excluded with ≥2.00 D astigmatism, ≥2 D myopic anisometropia, and ≥1 D hyperopic anisometropia and ocular disease affecting vision. Methods: Refractive error was determined by cycloplegic subjective refraction. Students were randomly assigned to receive RMS or custom spectacles (CS) a..
