| 摘要 | Flicker is the lighting characteristic of electric light sourcesthat is generally harmful to human health. In this study, subjects were set in lighting environments with different flickers, and required to finish the reading taskwithin 45 minutes. Visual fatigue caused by different LED flickers and during the task were recorded and reflected bythreevisual function parameters: higher order aberrations (HOAs), modulation transfer function (MTF) and the ratio of accommodative convergence to accommodation ratio (AC/A).Significant differences were found to exist between the visual function variations of the subjects in lighting environments with different flickers, and people with higher flicker lighting showed lower variations of visual functions.It is manifested that LED luminaires with reducedflicker frequenciesare more likely to cause visual fatigue. |
