视觉的环境因素对于预防和克服视疲劳的重要性,已逐渐被重视起来。随着科学不断前进工业继续发展,为了保护青少年的视力,防止工人视疲劳的发生和提高对精细工种的工效,视觉环境卫生的研究已成为一项刻不容缓的研究课题。为此特将视觉环境的基本内容简要介绍。一、被观察物的反射系数人眼所以能看到外界的物体,完全靠物体表面的反光。这种反光不象光滑镜面把投射光完全反射回来所形成的耀眼眩光,而是物体表面的弥漫性反
The importance of visual environmental factors in preventing and overcoming visual fatigue has gradually been taken seriously. As science continues to advance its industry, the research on visual sanitation has become a pressing research topic in order to protect young people’s eyesight, prevent workers from seeing the fatigue and improve the work efficiency of fine workmanship. To this end will be the basic content of the visual environment briefly introduced. First, the reflection coefficient of the observed object The human eye can see the outside world, completely by the reflective surface of the object. This kind of reflection is not like the glossy glare to completely reflect the projected light back to form the dazzling glare, but the diffuse surface of the object
