摘要： Disclosed is a progressive ophthalmic lens including a front surface and a rear surface, each surface having in each point an altitude, a mean sphere value and a cylinder value, the front surface of the lens including: —a far vision zone having a far vision reference point; —a near vision zone having a near vision reference point; —a main meridian, wherein the front surface is regressive and has: —a sphere gradient normalized value of less than 7.50·10−1 mm−1 at any point in a central portion of the lens including a portion of the main meridian (32), the far vision reference point (FV) and the near vision reference point (NV); —a cylinder gradient normalized value of less than 1.45 mm−1 at any point in the central portion of the lens.

摘要： A method for designing a mould (120) for casting a semi-finished ophthalmic lens blank, wherein the surface of the mould (120) is designed so that the surface of the mould fits a predetermined closed curve, wherein the predetermined closed curve is representative of the geometry of a gasket (160) to be used in association with the mould (10). A method for assembling a mould assembly (100) and a method for casting a semi-finished ophthalmic lens blank, and a computer program product including software code portions for performing steps of these methods are also described.
