Abstract: A progressive power lens that prevents degradation in optical characteristics invited by deviation of a pantoscopic angle from the standard value. The lens includes an outer refractive surface and an inner refractive surface, at least one of which is a progressive surface. Because the amount and direction of aberrations generated in distance and near portions are different, correction is given to either or both of the surface powers of the outer and inner surfaces of the lens such that the distance and near portions are differently corrected.

Abstract: A method for designing a spectacle lens that includes an optical convex surface on an object side of the spectacle lens and an optical concave surface on an eye side of the spectacle lens and is mounted in a spectacle frame in a manner tilting with respect to a forward sight line, the optical convex surface being spherical, the optical concave surface being optically curved according to a prescription, the method including: defining a design reference point at an intersection of the optical concave surface and the forward sight line; and determining an angle formed by a tangent line at the design reference point and a perpendicular plane perpendicular to the forward sight line as a lens tilt angle ? with which the spectacle lens is mounted in the spectacle frame.

Abstract: A method of correcting the effects of a bend angle of 200 degrees or larger of spectacle frames, and astigmatism correcting characteristics in such spectacle frames. An exemplary embodiment of the present invention includes a design method for a spectacle lens mounted in a spectacle frame having a bend angle of 200 degrees or larger including an astigmatic power adding step, on the object side refractive surface or eyeball side refractive surface of the spectacle lens, for canceling astigmatic aberration caused by the bend angle of the spectacle frame, at a design reference point of the spectacle lens, and a step setting prismatic power by tilting the refractive surface, which is on an object side or an eyeball side, of the spectacle lens for canceling prismatic power caused by the bend angle of the spectacle frame, at the design reference point of the spectacle lens.

Abstract: A mark (10A) is formed by focused laser beam inside a spectacle lens (L1). The mark is formed approximately parallel to an optical axis of the spectacle lens (L1). An optical reference position (L0) of a spectacle lens (L2) is aligned with a reference position (T) of marking apparatus (3) for alignment, and the spectacle lens (L2) is attached to a holder (11) of the marking apparatus (3). Then, positioning is carried out based on the optical reference position (L0) of the spectacle lens (L2). Subsequently, the spectacle lens (L2) is shifted to a marking start position for conducting marking. The optical reference position (L0) can be aligned with the reference position (T) of the marking apparatus (3) by adjusting the position of the spectacle lens (L2) based on a pair of concealed marks formed on the spectacle lens (L2).

Abstract: To provide a spectacle lens manufacturing system and a method of manufacturing a spectacle lens, as well as a program and a recording medium therefor, that can meet various demands for marking and by which customers can confirm the outer appearance or the like of the spectacle lens. In a spectacle lens manufacturing system, after acquiring mark information and lens information with a terminal, these mark information and lens information are output to a calculation server, and a determination unit of the calculation server determines whether or not marking is possible. If the determination unit determines that it is possible to mark, it is judged whether or not a spectacle lens is manufactured based on a simulation image of the spectacle lens displayed on an image display unit of the terminal, and if it is determined to manufacture the spectacle lens, a processing information-generating unit of the calculation server generates processing information for the spectacle lens.
