背景：本研究的目的是比较各种屈光矫正方法中眩光和光晕的存在。方法：使用计算机生成的刺激物对98只健康的老年前期老花眼进行眩光和光晕的分析。将受试者分为3组：未矫正正视眼、单视塑料镜片配戴者(镜片有污垢)和单视软性隐形眼镜配戴者。正视镜与隐形眼镜组(P<；0.001)和未清洁眼镜组(P<；005)之间的光晕有显著差异，但清洁眼镜组的光晕差异不显著。镜片清洗后光晕明显减小(P<；0.0187)。结论：隐形眼镜和不清洁眼镜配戴者的光晕明显大于正视镜和清洁眼镜配戴者。不干净的眼镜可能会影响心理物理和临床测试结果的准确性。
Background: The aim of this investigation was to compare glare and halo with various methods of refractive correction.Methods: Ninety-eight eyes of healthy pre-presbyopes were analysed for the presence of glare and halo using computer-generated stimuli. Subjects were divided into three groups: emmetropes without correction, single vision plastic lens spectacle wearers (with clean and dirty lenses) or single-vision soft contact lens wearers.Results: No significant difference in glare was found among groups. Significant differences were noted in halos between emmetropes and both contact lens (p < 0.001) and uncleaned spectacle groups (p < 0.05) but not with cleaned spectacles. The reduction in halo size after cleaning the lenses was significant (p < 0.0187).Conclusions: Contact lens and unclean spectacle wearers both have significantly larger halos than emmetropes and those wearing cleaned spectacle lenses. Unclean spectacles may affect the accuracy of results in psychophysical and clinical testing.
