摘　　要：照明是影响老年人视觉显示终端(Visual Display Terminal,VDT)视疲劳的重要因素之一。为确定有利于预防和减轻老年人VDT视疲劳的照明参数,从人因工程学视角,搭建实验模拟空间,探讨主观评价、视觉表现和生理指标与视疲劳的关系,研究照度、色温、屏幕亮度等光学参数对老年人VDT视疲劳的影响,采用Critic和Topsis组合权重法对不同照明条件进行综合评价。方差结果显示,高照度1500 lx、低屏幕亮度50 cd/m^(2)最有利于减轻老年人VDT视疲劳;高照度1500 lx和低屏幕亮度50 cd/m^(2)组合,高照度1500 lx和高色温6500 K组合更适宜老年人VDT阅读。综合评价结果显示,评分最高的照明组合方案是1500 lx、6500 K和50 cd/m^(2),其次是750 lx、6500 K和50 cd/m^(2)。Lighting is one of the important factors of VDT visual fatigue in elderly individuals.In order to determine the lighting parameters that are beneficial for preventing and alleviating VDT eye fatigue in the elderly,an ergonomic perspective was adopted to create an experimental simulated space.The study explores the relationship between subjective evaluation,visual performance,physiological indicators,and visual fatigue.The effects of optical parameters such as illuminance,color temperature,and screen brightness on VDT visual fatigue in the elderly are investigated.The Critic and Topsis combined weighting methods are used to comprehensively evaluate different lighting conditions.The variance results show that a high illumination of 1500 lx and low screen brightness of 50 cd/m^(2)are most effective in alleviating VDT visual fatigue in the elderly;The combinations of high illumination 1500 lx with low screen brightness 50 cd/m^(2),as well as high illumination 1500 lx with high color temperature 6500 K,are more suitable for elderly VDT reading.The comprehensive evaluation results show that the highest-rated lighting combination is 1500 lx,6500 K and 50 cd/m^(2),followed by 750 lx,6500 K and 50 cd/m^(2).
