Abstract: A spectacle lens including a plurality of segment regions that cause a light beam incident from an object-side surface to exit from an eyeball-side surface and to converge on a position other than on a retina of an eyeball of a spectacle wearer, wherein the plurality of segment regions are configured to achieve a vision value equal to or lower than a predetermined vision limit value; and an area ratio of non-segment regions with respect to a combined region of the plurality of segment regions and the non-segment regions other than the segment regions is 0% or more and 25% or less.

Abstract: The present specification includes eyeglasses comprising an eyeglass frame, a first ophthalmic lens incorporating a plurality of microlenses designed to induce blur for the wearer, and a second ophthalmic lens devoid of microlenses. The eyeglasses may provide a unique optical configuration where the first lens introduces intentional blur effects while the second lens may remain free of microlenses, offering therapeutic management or treatment for some medical conditions.
