本文根据对上海市十所重点中学的2000名学生在家中使用台灯的情况和他们的视力变化所进行的调查,用逐步回归法分析了局部照明与学生视力衰退的关系。肯定了除遗传和用眼卫生二个因素外,不良的局部照明方式也会严重地影响学生的视力发展。并找出局部照明对学生视力衰退有显著影响的因素为: 1.使用台灯时室内缺少环境照明。2.光源到作业中心的连线与桌面法线间的夹角太小。3.台灯用白炽灯泡作为光源。4.在局部照明下连续作业的时间过长。
Based on the investigation of the use of table lamps at home and the changes of their eyesight in 2000 students from 10 key high schools in Shanghai, this paper analyzes the relationship between local lighting and students’ eyesight loss by stepwise regression. Affirmed that in addition to genetic and eye health with two factors, the poor way of local lighting can also seriously affect students’ vision development. And find out the local lighting has a significant impact on students’ vision loss factors: 1. The lack of ambient lighting when using the lamp. 2. The light source to the center of the connection between workmanship and the angle between the desktop is too small. 3. Table lamp with incandescent light bulb as a light source. 4. In the local lighting continuous operation time is too long.
