1. A front curve design method for preparing a resin lens with a high refractive index, comprising within a myopia power range of −1.00 to −15.00, designing the maximum design front curve to be −4.00 D from −1.00 to −3.50; designing the maximum design front curve to be −3.00 D from −3.75 to −5.50; designing the maximum design front curve to be −2.00 D from −5.75 to −8.75; and designing the maximum design front curve to be −1.50 D from −9.00 to −15.00.
