照明因子對視覺績效與視覺疲勞之影響
Effects of illumination factors on visual performance and visual fatigue

摘 要

照明燈光顏色與照度是影響視覺績效與視覺疲勞的重要因素。本研究旨在探討以紅色、藍色、綠色和白色為照明燈光顏色，分別在不同照度條件下，對人員視覺績效與視覺疲勞之影響。
研究中，視覺績效以目標辨識速度及目標辨識正確率來評估，視覺疲勞則以受測者閃光融合閾值（Critical flicker fusion frequency；CFF）、視力、視距變化以及受測者主觀評量來衡量。研究結果發現照明燈光顏色對視力變化有顯著影響，照度對目標辨識速度有顯著影響；受測者主觀上認為在紅色照明燈光下作業不論其環境照度為何？均有顯著的視覺疲勞的現象，甚至認為紅色照明燈光會影響其工作。
本研究結果可提供工程設計人員在設計具有特殊作業需求之電腦終端機作業控制室時，如何提供適當的照明燈光顏色及照度，以提昇作業人員的視覺績效，並可有效降低視覺疲勞。

The Effects of illumination factors on visual performance and
visual fatigue

Abstract

Low-level red lighting has traditionally been employed in all submarine control areas, including the sonar and radar control room. This study investigates the effects of illumination factors on visual performance and visual fatigue during visual display terminal（VDT）work. Ten college students （5 males and 5 females）are recruited as participants to perform eight different experiment tasks. A statistical completely random design is utilized with four light colors (red, blue, green and white）,and two illumination levels （20lux and 340lux）. The dependent variables are the change of critical fusion frequency （CFF）, visual acuity, visual distance, searching time of targets, correct percentage of targets ,and items in a subjective questionnaire. The ANOVA and Duncan analysis show that:（1）The color of light has significant effect on visual acuity;（2）The illumination has significant effect on searching time of targets; and （3）The subjects do not like to perform VDT work under the red light .
Based on these finding, the designers can adopt different combinations of light colors and illumination levels to promote operators’ visual performance and prevent visual fatigue effectively when designing VDT workstations.
