摘　　要：为探究光环境、体质与视健康的交互作用关系,保护高风险体质者视觉作业安全。首先,对重庆地区9家建筑勘察设计企业进行光环境调研,测量72间视觉显示终端(VDT)办公室的水平作业面照度、相关色温、眼位照度等光环境参数,计算节律照明相关指标,并与标准进行比对;然后,对541名青年设计师进行中医体质辨识及视疲劳特征记录;最后,基于中医体病相关理论,分析环境光照下体质与近视、视疲劳的相关性,辨别视健康高风险体质。结果表明:青年设计师的体质类型以平和质为主,在9种体质中占比最高;偏颇体质中阳虚质占比最高,对近视、视疲劳的易感性显著高于平和质;工作场所长期日光暴露不足、节律刺激过低易诱发体质向阳虚质转变,增加视健康风险。Lighting in visual display terminal(VDT)offices is considered to be one of the main factors influencing employees’visual health.On the one hand,improper lighting conditions can lead to increased visual fatigue.On the other hand,recent studies reveal that light is not only essential for vision but also achieves important non-visual effects on a host of physiological functions.These effects depend largely on person-specific parameters.Differences between individuals may modulate the effects of light exposure,with some people exhibiting stronger responses than others.Hence,targeted studies to identify susceptible groups and establish a scientific classification method are necessary for delivering appropriate light doses and protecting employees’visual safety.This study investigates the relationship among light environment,the traditional Chinese medicine(TCM)constitution,and visual healthy,and explores the feasibility of identifying susceptible groups using TCM constitutions.Firstly,a field study is conducted on nine architectural design companies with standard management and complete regulations in Chongqing,China.Each company employs more than 100 people,and their working hours are approximately from 9:00 am to 18:00 pm.The lighting environment of 72 visual display terminal(VDT)offices is assessed and measured at these companies.Horizontal illuminance on the working plane,correlated color temperature(CCT)and illuminance uniformity ratio(U0)are selected as the indexes of the visual lighting.Illuminance at the eye,mEDI(melanopic equivalent daylight illuminance),EML(equivalent melanopic lux)and CS(Circadian Scale)are selected as the indexes of circadian lighting.Then,541 young designers with similar workloads,work content,working hours,and lighting environments are recruited from these offices.The TCM physical constitution scale and a self-reported visual health questionnaire are used to evaluate the TCM constitution types and visual fatigue of these young designers.Finally,statistical analysis are performed usin
