The effect of a 13-week exposure to moderate levels of light modulation resulting in visible, but not irritable, stroboscopic effect was studied. Over the course of three months, two sets of participants working in an office environment filled in a questionnaire about their health and wellbeing at the start and the end of each working day. Using a schedule of changes between two light settings differing only in the amount of temporal modulation, it was shown that the higher temporal modulation light did not significantly increase the occurrence of any health and wellbeing parameters (like eyestrain and headaches) tested. Furthermore, even though there was a large variation in the individual probability of complaints, there was no interaction effect between the individual level of complaints and the amount of light modulation. Using power analysis, we demonstrate that the increase of unwanted effects of 5% or more has a probability of less than 5%.

长期暴露于中等强度调制光的频闪效应的影响

研究了 13 周暴露于中度光调制导致可见但不烦躁的频闪效应的影响。在三个月的时间里，两组在办公室环境中工作的参与者在每个工作日的开始和结束时填写一份关于他们的健康和福祉的问卷。使用仅在时间调制量上不同的两种光设置之间的变化时间表，结果表明，较高的时间调制光不会显着增加所测试的任何健康和幸福参数（如眼睛疲劳和头痛）的发生率。此外，即使个体投诉概率存在很大差异，但个人投诉水平与光调制量之间没有交互作用。使用功率分析，
