Abstract
The present invention provides a contact lens having novel myopia progression suppression capability, while enabling a good QOV to be obtained and ensuring myopia is kept from progressing. A contact lens having a refractive correction power for correcting myopia and myopic astigmatism set in a central region of an optical part, wherein a positive addition power in comparison with a power in the central region is set in a peripheral region of the optical part so that progression of the myopia or myopic astigmatism is suppressed, a positioning member is provided that specifies a circumferential position of the lens under a worn condition, and a lens optical axis of the optical part is set offset from a lens geometric center to align with a line of sight of a human eye under the worn condition produced by the positioning member.
