ABSTRACT:
Disclosed is a contact lens having a refractive power ranging from −15.0 to +15.0 diopters in an optical zone thereof, wherein a back optical zone is a conical surface having a conic coefficient ranting from −0.04 to −0.49, and a front optical zone is a conical surface having a conic coefficient ranging from −0.02 to −0.50. The contact lens exhibits optical characteristics required in consideration of an optical system of an eye when being positioned at a position of rest during wear in which an optical axis of the optical zone is decentered with respect to an optical axis of the eye.
