摘要
A soft contact lens has low water content or no water content. The soft contact lens includes: a circular central part positioned at a center of the soft contact lens; an intermediate part positioned at an outer peripheral side of the central part and forming an annular shape having a center coaxial with the central part; and an outer edge part positioned at an outer peripheral side of the intermediate part and forming an annular shape having a center coaxial with the central part. Respective radii of curvature of the central part, the intermediate part, and the outer edge part are different from each other, and a sagittal depth of the soft contact lens is within a range of a sagittal depth in a case where the entire soft contact lens is formed in a range of a radius of curvature ±0.2 mm of the outer edge part.
