Abstract:
A spectacle lens capable of obtaining a good vision without feeling of discomfort, even being fitted into a frame having a large front angle, and a method of creating the shape data of the spectacle lens having dioptric power to be fitted into a frame having a lens front angle. The method corrects the shape data of a lens back surface so that the prismatic effect undergone via the lens of initial lens shape by a plurality of rays passing through a rotation center of the eye in a case where a lens front angle is provided is identical or close to the prismatic effect undergone via the lens of initial lens shape by the plurality of rays passing through the rotation center of the eye in a case where no lens front angle is provided.
