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 9):
The contact lens manufacturing method according to  claim 1 , wherein within a region of the contact lens further to an outer circumference side than \u00f87 mm and further to an inner circumference side than  1  mm from an inside of an edge part, the peripheral area is provided using the lens rear surface shape corresponding to the corneal surface shape specified by the radius of curvature, the conic constant, and the Zernike surface.
