Zusammenfassung:A designing method of a contact lens for myopia progression suppression including: providing a tonic accommodation relaxation region in which an additional power whose maximum value is from +0.25 to +0.75 diopters is set with respect to a proper correction power, the additional power being capable of relaxing a tonic accommodation without improving an aberration off an optical axis of an eye and an accommodation lag on the optical axis; and providing a proper correction region in which the additional power is not set on an optical center.
