  • Patent number: 9519146
    Abstract: Image light is formed of light flux components having a diameter of, e.g., 3 mm or smaller. The image light is then caused to be incident on the iris of an eye to form an image in the form of a virtual image. The position where the principal rays of the light flux components that form the image light intersect one another is set to be a position shifted from the position of the iris of the eye toward the retina. The range of the light flux components that reach the retina can thus be changed in accordance with the motion of the eye. As a result, in accordance with a change in the line of sight that occurs when a wearer moves the line of sight in a specific direction, the image light can be so controlled that only image light components in the specific direction reach the retina of the eye.
