PROBLEM TO BE SOLVED: To provide a visibility measuring system capable of concretely materializing an objective perimetry in a simple constitution.
SOLUTION: This visibility measuring system is provided with: a brain activity measuring device 1 detecting secondary reactions caused by the activity of brain cells in a prescribed region of the brain of a subject and outputting them as brain activity data a display device 2 displaying a forward-directional image 71 where a prescribed visual target moves repeatedly in a predetermined forward direction and an inverse-directional image 72 where the visual target moves repeatedly in the inverse direction to the forward direction, to the subject and a data correction section 4 calculating corrected brain activity data by subtracting a reaction lag time from appearance phases of the respective brain activity data when the forward-directional image 71 is displayed and when the inverse image 72 is displayed relative to a criterion phase predetermined based on the movement of the visual target.
