【摘要】 根据传统的信念,一般认为工作桌面上均匀的亮度分布对于视觉效能有很大的影响。作者在三种不同亮度分布的桌面上以四种不同对比的核对数字作业于三种照度水平下进行了试验。实验结果证明桌面的不同反射率对于视觉功效水平并无明显的影响。作者认为亮度的均匀分布能提高中央视觉的视敏度,但是对于边缘视觉并无作用,而一般阅读作业并不仅仅是中央视觉的反应中,还包含了一定的边缘视觉反应。因此,追求均匀的亮度分布是毫无实际意义的。更多还原

【Abstract】 The aditional belief tells us that the uniform distribution of luminance in the visual field greatly influences the visual performance. The writers conducted a Number Checking Test with 3 lumiannce patterns under 3 illuminance levels. The result snows that the different reflectances of the desk surface have no obvious effects on the visual performance. The writers deem that the uniform luminance pattern can enhance the visual acuity of fovea vision, but does not effect the peripheral vision. The reading task, which is not merely the fovea vision response, includes some peripheral vision response. Consequently, the seeking of high uniformity of luminance pattern has no practical meaning.更多还原
