Spectacle lens, spectacle lens design method, and spectacle lens design system

Abstract

Provided is a myopia progression suppression technique that adapts to the RPR of a wearer. An eyeglass lens and related techniques are provided, the eyeglass lens comprising: a base region that causes a light beam entering through an object-side surface to exit through an eye-side surface and converge on the retina through the eye; and a plurality of defocus regions, each defocus region contacting the base region and having the following characteristics: a light beam passing through at least a portion of the defocus region is incident on the retina as a divergent ray, and in a defocus region not less than half of the plurality of defocus regions, at least one of defocus power and size is set for each defocus region to compensate for a change in retinal spot size due to relative peripheral refraction (RPR) that depends on an angle of eccentricity of the wearer's eye. 提供了一种适应佩戴者的RPR的近视发展抑制技术。提供了一种眼镜镜片和相关技术，该眼镜镜片包括：基底区域，该基底区域使通过物体侧表面进入的光束通过眼睛侧表面射出并经由眼睛会聚在视网膜上；以及多个散焦区域，每个散焦区域接触基底区域并且具有以下特性：穿过散焦区域的至少一部分的光束作为发散射线入射在视网膜上，并且在不少于所述多个散焦区域的一半的散焦区域中，设定每个散焦区域的散焦度数和尺寸中的至少一个，以补偿由于相对周边屈光(RPR)引起的视网膜光斑尺寸的变化，该相对周边屈光(RPR)取决于佩戴者的眼睛的偏心角。
