Vision training device for improving fusional vergence

摘要

At least one of the first display and a second display move at least one of the left eye image and the right eye image such that a distance between the left eye image and the right eye image is increased. A separation confirmation signal is received indicating that the image focuses of the image do not coincide with each other in terms of fusion. Fusional amplitude information is stored indicating a separation distance between the left eye image and the right eye image when the image separation confirmation is input.
