[Relationship between visual fatigue of students and artificial illumination in classroom with television].
A comparison of visual fatigue of 105 students 20-25 yrs old, attending classes with T. V. education program at 30, 45, 65, 100, 150 (lx) on desk was made. Visual fatigue was determined by the changes of visuognosis persistent time, nearest and farthest point in nearvision, and accommodation from before to after classes. The results indicated that the lightest fatigue appeared in 65 1x. Under the illuminance, fluorescent lamp used as light source was more advantageous than incandescent lamp, but the difference of visual fatigue between watching colour and black-white television was not (obvious).
