摘要： A progressive power lens 10 for spectacles has a distance portion 11 and a near portion 12 of different powers. A surface power OMHP in a horizontal direction on an object-side surface along a principal meridian 14 or a vertical reference line passing through a fitting point Pe, a surface power OMVP(y) in a vertical direction of the object-side surface, the absolute value IMHP of a surface power on an eye-side surface, and the absolute value IMVP of a surface power in a vertical direction on the eye-side surface satisfy the following condition. OMHP(y)>OMVP(y) IMHP(y)>IMVP(y) OMHP(y)-OMVP(y)=IMHP(y)-IMVP(y) In the conditions, y is a coordinate along the principal meridian or the vertical reference line.

摘要： An eye-side refractive surface 11 of a distance portion is concave and at least part of an eye-side refractive surface 3 of a near portion is a convex region 31 where one or both of principal meridians of the surface are convex. This provides a back surface progressive-power lens capable of solving disadvantages in terms of lens thickness, external appearance and the like in a back surface progressive-power lens in which the eye-side refractive surface is formed of a progressive-power surface.

摘要： A contact lens (1) provided with a front curve (2) formed by a plurality of annular curved surfaces (F1, F2 .....) for distant vision and a plurality of annular curved surfaces (N1, N2 .....) for near vision, which curved surfaces (F1, F2 .....; N1, N2 .....) are arranged concentrically and alternately, characterized in that the curved surfaces for distant vision in at least the central region of the front curve extend so that the curved surfaces for distant vision farther away from the optical axis have centers of curvature (OF1, OF2 .....) positioned farther away from the optical axis and front curve, these centers of curvature of these curved surfaces being arranged so that rays of light entering these curved surfaces and being parallel to the optical axis are condensed on substantially the same point on the optical axis, the curved surfaces for near vision in at least the central region of the front curve extending so that the curved surfaces for near vision farther away from the optical axis have centers of curvature (ON1, ON2 .....) positioned farther away from the optical axis and closer to the front curve, these centers of curvature of these curved surfaces being arranged so that rays of light entering these curved surfaces and being parallel to the optical axis are condensed on substantially the same point on the optical axis. This invention can provide a contact lens which has a front curve formed by alternately arranging annular and concentric curved surfaces for distant vision and annular and concentric curved surfaces for near vision, and which is free from spherical aberration.

摘要： A multifocal contact lens having concentric bands of different lens curves, wherein a plurality of curves for farsightedness alternate with a plurality of curves for nearsightedness. A mold for the lens and a production method thereof are also provided. Farsight curve surfaces (F1, F2, ...) of the lens curve (2) have centers of curvature (OF1, OF2, ...) on the optical axis, and radiuses of curvature (RF1, RF2, ...) set so that rays of light incident into farsight curve surfaces and parallel to the optical axis form an image effectively at a single farsight focus on the optical axis. Nearsight curve surfaces (N1, N2, ...) of the lens curve have centers of curvature (ON1, ON2, ...) on the optical axis, and radiuses of curvature (RN1, RN2, ...) set so that rays of light incident into nearsight curve surfaces and parallel to the optical axis form an image effectively at a single nearsight focus (FN) on the optical axis.
