Abstract: In a spherical lens surface processing method, a lens surface is ground to a spherical surface by forming a contact state in which a rotating cup-shaped grinding stone is placed in contact with the lens surface and a sphere center oscillation state in which the cup-shaped grinding stone oscillates along the lens surface centered on a sphere center. In the sphere center oscillation state, the distance from the center of the sphere center oscillation to the contact point of the cup-shaped grinding stone with the lens surface is set to be the same as the radius of the spherical surface. The oscillation width of the sphere center oscillation is set so that the contact point of the cup-shaped grinding store with the lens surface can move from one peripheral edge of the lens surface past the lens center on the lens surface to the other peripheral edge.
