摘要：
A method and device for evaluating the dynamics of a tear fluid layer to objectively and accurately evaluate breakdown of the tear fluid layer, which is a core mechanism of dry eye, are provided. The method includes a step of acquiring color information of each pixel in a predetermined region of a tear fluid layer interference fringe image, which is a moving image or a plurality of static images, a step of calculating a numerical value indicating the diversity of color from the acquired color information, a step of calculating the average value of the color information, and a step of calculating a coefficient of variation on the basis of the calculated numerical value indicating the diversity of color and the calculated average value of the color information. The coefficient of variation is used as an index for evaluating the dynamics of the tear fluid layer.
