Abstract: A spectacle lens can inhibit ametropia of the eyes and ensure full visibility. The spectacle lens comprises: first refraction areas and second refraction areas. Each first refraction area has a first refraction force that may be based on a prescription for correcting the ametropia of the eyes. Each second refraction area has a refraction force different from the first refraction force and may function to focus images on the positions except the retina of the eyes, to inhibit the development of the ametropia. Near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.

Abstract: A progressive addition lens, a manufacturing method and a design method therefor, and a progressive addition lens manufacturing system, capable of flexibly adapting to an actual use state of a wearer and are optimal for each wearer, for determining a main line of sight considering not only convergence of the eye occurring with near vision including passive accommodative power but also convergence of the eye induced by using an accommodative power margin of the eye. The design method includes a first main line of sight calculation step of calculating a first main line of sight, where accommodative convergence caused by use of the accommodative power margin is considered, based on lens design information including at least information of accommodative power of the eye and a final main line of sight determination step of determining a final main line of sight of a lens from the first main line of sight.

Abstract: A technology that makes a change in the amount of aberration in a spectacle lens worn by wearer relative to a change in at least one of the aberration in the eye or spectacle lens. A method for designing a spectacle lens wherein, when a degree of change caused by a physical feature of wearer in at least one of an aberration distribution of an eye of wearer and an aberration distribution of a spectacle lens worn by the wearer is large, a spectacle lens that has an aberration distribution of which rotational asymmetry is weak in a region having a predetermined width and a center at any point on a main meridian of the spectacle lens is obtained as a design solution, and when the degree of the change is small, a spectacle lens of which rotational asymmetry is strong in the region is obtained as a design solution.
