ObjectivesUntreated cataracts and uncorrected refractive errors are the leading causes of vision impairment worldwide. Timely correction of refractive errors can significantly improve visual function and daily life. This study examined the impact of spectacle use on the academic performance of schoolchildren with reduced visual acuity (VA) and myopia.MethodsThis cross-sectional study included 647 students from five secondary schools in Hue City, Vietnam. Students underwent comprehensive eye examinations, including VA, autorefractometry, and axial length measurements, and a structured questionnaire was completed. The primary outcome was academic performance, based on grade point average (GPA), math, and literature scores. Generalized linear models were utilized to examine the association between spectacle use and students’ academic performance.ResultsThe mean spherical equivalent was −0.92 ± 1.62 diopters, and the mean axial length was 23.32 ± 1.07 mm. The prevalence of reduced VA (uncorrected VA ≤ 7/10) and myopia (spherical equivalent ≤ −0.5 diopters) was 23.2% and 48.7%, respectively. Almost two-thirds of myopic students did not wear spectacles. Spectacle use was found to be significantly associated with an increased GPA (β = 0.462; 95% confidence interval = 0.108–0.816), math scores (β = 0.517; 95% confidence interval = 0.015–1.020), and literature scores (β = 0.438; 95% confidence interval = 0.074–0.802) among students with reduced VA, and with increased literature scores (β = 0.277; 95% confidence interval = 0.046–0.509) among students with myopia.ConclusionsRefractive errors, particularly myopia, are major health concerns among secondary school students in Vietnam. Despite the need for corrective spectacles, many students do not wear them, exacerbating their vision problems. This study highlights the benefits of spectacles in improving academic performance for students with reduced VA and myopia.研究目的：未治疗的白内障与未矫正的屈光不正是全球视力损害的首要诱因。及时矫正屈光不正可显著改善视觉功能与日常生活质量。本研究旨在探究配镜对视力（visual acuity, VA）减退且罹患近视的学龄儿童学业表现的影响。 研究方法：本横断面研究纳入了越南顺化市5所中学的647名学生。所有学生接受了全面眼部检查，包括视力检测、自动验光及眼轴长度测量，并完成了结构化问卷。本研究的主要结局指标为基于平均学分绩点（grade point average, GPA）、数学与语文成绩的学业表现，采用广义线性模型分析配镜与学生学业表现之间的关联。 研究结果：受试者的平均球镜当量为-0.92±1.62屈光度，平均眼轴长度为23.32±1.07mm。视力减退（未矫正视力≤7/10）与近视（球镜当量≤-0.5屈光度）的患病率分别为23.2%与48.7%。近三分之二的近视学生未佩戴眼镜。研究发现，在视力减退的学生中，配镜与更高的GPA（β=0.462；95%置信区间：0.108–0.816）、数学成绩（β=0.517；95%置信区间：0.015–1.020）及语文成绩（β=0.438；95%置信区间：0.074–0.802）显著相关；在近视学生中，配镜仅与更高的语文成绩显著相关（β=0.277；95%置信区间：0.046–0.509）。 研究结论：屈光不正，尤其是近视，是越南中学生面临的主要健康问题。尽管亟需佩戴矫正眼镜，但仍有大量学生未遵医嘱配镜，进而加重了其视力问题。本研究证实，配镜可有效改善视力减退与近视学生的学业表现。
