Abstract

A method for dynamically evaluating a tear fluid layer using an interference fringe image of the tear fluid layer composed of a plurality of consecutive frames, and includes: an image creation step of creating at least one break detection image of a first break detection image, a second break detection image, a third break detection image, and a fourth break detection image, which are images for detecting a breaking site of the tear fluid layer; a determination step of determining whether the break detection image created by the image creation step corresponds to a predetermined breakup pattern; a tally step of tallying the determination results determined by the determination step; and an evaluation step of evaluating, on the basis of a tallied result by the tally step, a breakup pattern of the interference fringe image of the tear fluid layer.
