To examine factors influencing adherence to spectacle wear and perceived value within a prospective 1-month trial of ready-made and custom spectacles in school-aged children with uncorrected refractive error in urban China.
A total of 428 students aged 12 to 15 years with at least 1 diopter of uncorrected refractive error were given free spectacles and evaluated 1 month later at an unannounced visit. Demographic factors, vision, optical effects, and perceptions were modeled as predictors of observed use and perceived value using logistic regression adjusted for spectacle allocation.
Of 415 students, 388 (93.5%) planned to use their spectacles, 227 (54.7%) valued their spectacles highly, 204 (49.2%) had their spectacles on hand, and 13 (3.0%) were lost to follow-up. Female students were 1.72 times (95% confidence interval [CI], 1.10-2.68), students from lower income households were 1.78 times (1.32-2.39), and those not concerned over appearance were 2.04 times (1.25-3.36) more likely to have spectacles on hand. Students with a pupil size of 4 mm or greater were 2.55 times (95% CI, 1.61-4.03) and students with spectacle vision worse than 20/20 were 2.06 times (1.20-3.49) more likely to have spectacles on hand. Self-report of high perceived value was 2.23 times (95% CI, 1.30-3.80) more likely with 20/20 spectacle vision, 1.63 times (1.06-2.52) more likely with base-in prismatic effects of 0.5 prism diopters or more, 3.52 times (2.03-6.13) more likely when students would not tolerate blur to avoid wearing spectacles, and 2.16 times (1.24-3.76) more likely with disbelief that spectacles would make vision worse. Spectacle type had no effect.
Although most students planned to use their spectacles, only half were observed using them. Day-to-day use might increase if students were less concerned over appearance. Optical factors and beliefs surrounding spectacles are also predictive of acceptance. These findings provide further understanding of spectacle acceptance in teenagers.
在中国城市地区对患有未矫正屈光不正的学龄儿童进行为期1个月的现成眼镜和定制眼镜前瞻性试验，研究影响眼镜佩戴依从性和感知价值的因素。
共有428名年龄在12至15岁、未矫正屈光不正至少1屈光度的学生获得免费眼镜，并在1个月后进行不预先通知的随访评估。将人口统计学因素、视力、光学效果和认知作为观察使用情况和感知价值的预测因素，采用经眼镜分配调整的逻辑回归分析。
在415名学生中，388名（93.5%）计划使用他们的眼镜，227名（54.7%）对眼镜评价很高，204名（49.2%）手头有眼镜，13名（3.0%）失访。女生手头有眼镜的可能性是男生的1.72倍（95%置信区间[CI]，1.10 - 2.68），低收入家庭学生是1.78倍（1.32 - 2.39），对外表不关心的学生是2.04倍（1.25 - 3.36）。瞳孔大小为4毫米或更大的学生手头有眼镜的可能性是2.55倍（95%CI，1.61 - 4.03），眼镜视力低于20/20的学生是2.06倍（1.20 - 3.49）。自我报告的高感知价值在眼镜视力为20/20时可能性高2.23倍（95%CI，1.30 - 3.80），在底向内棱镜效应为0.5棱镜度或更高时高1.63倍（1.06 - 2.52），在学生不能忍受模糊以避免戴眼镜时高3.52倍（2.03 - 6.13），在不相信眼镜会使视力变差时高2.16倍（1.24 - 3.76）。眼镜类型没有影响。
尽管大多数学生计划使用他们的眼镜，但只有一半被观察到在使用。如果学生对外表不那么在意，日常使用可能会增加。光学因素和对眼镜的认知也可预测接受程度。这些发现为青少年对眼镜的接受情况提供了进一步的理解。
