| 摘要 | An off-axis curvature center lens is characterized by an x-y-z coordinate system of the convergence-reducing lens, the off-axis curvature lens comprising a distance-vision region with a non-negative distance-vision optical power, having a front distance-vision surface with a center of front distance-vision curvature, and a rear distance-vision surface with a center of rear distance-vision curvature and a near-vision region with an optical power within 0.5D of the distance-vision optical power, having a front near-vision surface with a center of front near-vision curvature, and a rear near-vision surface with a center of rear near-vision curvature; wherein at least one of an x-coordinate of the center of front near-vision curvature is nasal relative to an x-coordinate of the center of front distance-vision curvature, and an x-coordinate of the center of rear near-vision curvature is temporal relative to an x-coordinate of the center of rear distance-vision curvature. | ||||||
