The inner lens shape reflecting the corneal shape of contact lens wearers, conveniently than ever, and sufficiently can be imparted with a reflection of precise corneal shape, thereby allowing an improvement in wear comfort, to provide a production method and a contact lens of the novel contact lenses.
Using statistics obtained corneal surface shape by the population of the target eye characterized that are formulated target, it performs fitting of the rotation symmetrical shape defining equation using the radius of curvature R and the conic constant CC, Zernike It performs fitting non-rotationally symmetric shape defined formula using functions, their definition formula lens rear surface 20 a shape corresponding to a particular corneal surface shape, adopted to the rear surface of the peripheral zone of the contact lens 10.
