| 摘要 | Correlated color temperature is an important feature of the LED luminaire. However, its influence on visual discomfort remains vague due to the lack of a comprehensive study based on ocular physiological parameters and psychological assessment. In this study, the investigation was carried out by the measurement of ocular parameters and the collection of subjective score. Three physiological parameters were used including higher order aberrations (HOAs), modulation transfer function (MTF) and the ratio of accommodative convergence to accommodation ratio (AC/A). It is shown that correlated color temperature has significance influence on human eye, and the proper correlated color temperature for the ocular health of moderate myopia people is near 5000K. In addition, the results imply that the perception of discomfort is caused by psychological perception rather than ocular fatigue. |
