OBJECTIVES
Untreated 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.
METHODS
This 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.
RESULTS
The 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.
CONCLUSIONS
Refractive 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.
目的
未经治疗的白内障和未矫正的屈光不正，是全球视力损害的主要原因。及时矫正屈光不正可显著改善视功能和日常生活。本研究调查了佩戴眼镜对视力下降和近视的学童学业成绩的影响。
方法
这项横断面研究纳入了越南顺化市五所中学的647名学生。学生们接受了全面的眼部检查，包括视力、自动验光和眼轴长度测量，并完成了一份结构化问卷。主要结果是学业成绩，以平均绩点（GPA）、数学和语文成绩为依据。使用广义线性模型来研究佩戴眼镜与学生学业成绩之间的关联。
结果
平均等效球镜度为-0.92±1.62屈光度，平均眼轴长度为23.32±1.07毫米。视力下降（未矫正视力≤7/10）和近视（等效球镜度≤-0.5屈光度）的患病率分别为23.2%和48.7%。近三分之二的近视学生不戴眼镜。研究发现，佩戴眼镜与视力下降学生的GPA提高（β=0.462；95%置信区间=0.108-0.816）、数学成绩提高（β=0.517；95%置信区间=0.015-1.020）和语文成绩提高（β=0.438；95%置信区间=0.074-0.802）显著相关，与近视学生的语文成绩提高（β=0.277；95%置信区间=0.046-0.509）也显著相关。
结论
屈光不正，尤其是近视，是越南中学生的主要健康问题。尽管需要矫正眼镜，但许多学生不佩戴，这加剧了他们的视力问题。本研究强调了眼镜对视力下降和近视学生提高学业成绩的益处。
