Abstract:
The purpose of the present invention is to provide novel contact lens manufacturing method and contact lens capable of giving a lens inner surface shape reflecting a cornea shape of a contact lens wearer more easily than before with sufficient accuracy to reflect the cornea shape, thereby improving comfort during use. By using statistical information on a corneal surface shape obtained from a population of target eyes having a feature to be treated, a fitting for a rotationally-symmetric shape is performed based on a definitional equation using a radius of curvature (R) and a conic constant (C.C.) while a fitting for a rotationally-asymmetric shape is performed based on a definitional equation using a Zernike function. A shape of a lens rear surface ( 20 ) corresponding to the corneal surface shape specified by these definitional equations is adopted for a rear surface of a peripheral area of a contact lens ( 10 ).

Claim (Index 1):
A contact lens manufacturing method comprising:\n using statistical information of a corneal surface shape obtained by a population of target eyes having a feature that is a subject of prescription; performing a fitting of a rotationally symmetrical shape by setting values of a radius of curvature and a conic constant from the statistical information according to a formula below; specifying a corneal surface shape corresponding to the population of the target eyes by fitting a rotationally asymmetric element which is a residual difference during the fitting of the rotationally symmetrical shape using a Zernike surface; and using a lens rear surface shape corresponding to the corneal surface shape specified by the radius of curvature, the conic constant, and the Zernike surface for a rear surface of a peripheral area of the contact lens: R value with \u22122\u03c3\u2264R\u2264R value with +2\u03c3 C.C. value with \u22122\u03c3\u2264C.C.\u2264C.C. value with +2\u03c3 Where,\n R: Radius of curvature \n C.C.: Conic constant \n \u03c3: Standard deviation.
