防蓝光眼镜对成人色觉影响的评估

目的：评估长期配戴2种类型的防蓝光眼镜对成人色觉的影响。方法：前瞻性随机对照研究。收集2017年1月至2018年6月期间于温州医科大学附属眼视光医院就诊的长期戴镜成年人144例，年龄?20～39岁，等效球镜度-6.00~-0.50 D，随机分为A组（45例，配戴普通眼镜）、B组49例，配戴无底防蓝光眼镜（15%蓝光滤过功能）]和C组50例，配戴琥珀色基片防蓝光眼镜（30%蓝光滤过功能）]。?在初始戴镜、戴镜后1、3、6个月时分别进行FM-100色棋检查和色觉相关生活问卷检查，比较3组的色棋错误总分平方根（Sqrt TES）、4个色区（红-黄绿、黄绿-蓝绿、蓝绿-蓝紫、蓝紫-红）的错误分值平方根（Sqrt PES）和3个问卷条目得分。采用重复测量方差分析进行统计分析。结果：6个月内，3组间的Sqrt TES比较差异无统计学意义（F=0.82，P=0.411），3组间在同个色区的Sqrt PES数值上比较差异均无统计学意义（F红-黄绿=0.28,?P=0.758；F黄绿-蓝绿=0.95,?P=0.390；F蓝绿-蓝紫=0.62,?P=0.539；F蓝紫-红=0.43，P=0.653），3组间在同个条目（颜色辨别困难度、衣服搭配困难度、整体满意度）的问卷得分上比较差异均无统计学意义（F=0.25,?P=0.777；F=0.10,?P=0.905；F=0.63,?P=0.533）。结论：6个月内，与配戴普通眼镜相比，配戴2种类型的防蓝光眼镜均不影响成年人的正常色觉。蓝光滤过比例控制在30%以内的防蓝光眼镜均不会影响成人色觉。

Evaluation of Effect of Blue-Light Filtering Spectacles on Adults' Color Perception

Objective: To evaluate the effect of two types of blue-light filtering spectacles on adults' color perception. Methods: This was a prospective, randomized and controlled study. One humdred and forty-four normal adults who are used to wearing spectacles were enrolled in Eye Hospital, Wenzhou Medical University from January 2017 to June 2018. The age was ranging from 20 to 39 and the spherical equivalent refraction was ranging from -6.00 D to -0.50 D. The participants were randomly divided into A group (45 participants, using the regular clear spectacles), B group (49 participants, using 15% blue-light filtering spectacles) and C group (50 participants, using 30% blue-light filtering spectacles). All participants underwent FarnsworthMunsell 100 hue and questionnaires about color perception at baseline, 1 month, 3 months and 6 months of using spectacles. The parameters of the square root of total error score (Sqrt TES), the square root of partial error score (Sqrt PES) in four hue zones (red to yellow-green, yellow-green to blue-green, blue-green to blue-violet and blue-violet to red) and the scores of three questionnaires items were compared among three groups. The data were analyzed by repeated-measures analysis of variance. Results: During six months, there were no significant differences in Sqrt TES among the three types of spectacles (F=0.82, P=0.411). No statistical difference was found in Sqrt PES of every hue box among three groups (Fred to yellow-green=0.28, P=0.758; Fyellow-green to blue-green=0.95, P=0.390; Fblue-green to blue-viole=0.62, P=0.539; Fblue-violet to red=0.43, P=0.653). There was no statistical difference in the scores of each item (difficulty in color discrimination, difficulty in clothing matching and overall satisfaction) among three groups (F=0.25, P=0.777; F=0.10, P=0.905; F=0.63, P=0.533). Conclusions: During six months, two types of blue-light filtering spectacles does not affect adults’ color perception compared with the regular clear spectacles. Blue-light filtering spectacles which could filter blue light within 30% had no effect on adults’ color perception.
