Abstract

To find out the good visual environment for reading, the methods of illumination were studied using Arden Contrast Sensitivity System. Among various factors for comfortable reading condition such as air condition, temperature, humidity, noise and light, the intensity and characters of illumination were the most important factors for eye health. If the character of illuminations are fairly good, to make the brighter condition is better for eye hdalth. But in artificial illumination, there are so many limitations for supplying light of good characters. So we set the luminosity on the desk to 500 lx in which tbe best visual acuity presented, and checked the contrast sensitivity by changing the luminosity of the room. The results suggested that the condition in which luminosity on the desk was higher twice than the room was favorable for reading.
