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.

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.
