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: An aligning prism amount determination device to determine an aligning prism amount for correcting fixation disparity of a spectacle wearer, having the fixation disparity, includes a determiner to determine an aligning prism amount to be uniformly included in the spectacle lens for correcting the fixation disparity, based on a first aligning prism amount obtained by measuring an aligning prism amount of the spectacle wearer at an eye examination distance corresponding to a first distance, a second aligning prism amount obtained by measurement at an eye examination distance corresponding to a second distance shorter than the first distance, and information used for allocation of the first aligning prism amount and the second aligning prism amount, within a prism prescription range between the first aligning prism amount and the second aligning prism amount.

Abstract: A method for designing, by means of a computer, at least one surface of a lens for a user. The method includes the steps of (i) obtaining displacement information on an amount of displacement between a user specific fitting position and a reference position, the reference position representing a primary fitting point of a lens surface on a reference line of sight of an eye of the user, and the user specific fitting position representing a user specific fitting point of the lens surface determined on the basis of the user; and (ii) causing calculating a design of the at least one surface of the lens on the basis of said displacement information.
