Abstract: 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 said 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. The invention also refers to a method for assembling a mould assembly (100) and a method for casting a semi-finished ophthalmic lens blank. Finally the invention refers to a computer program product comprising software code portions for performing steps of these methods.

Abstract: Disclosed is a method for designing a mould (12, 14) for casting a semi-finished ophthalmic lens blank. The surface of the mould (12, 14) is designed so that the surface of the mould (12, 14) substantially fits a predetermined closed curve representative of the geometry of a gasket (16) to be used in combination with the mould (12, 14). The surface of the mould (12, 14) is designed using an optimisation process and the predetermined closed curve being a constraint for the optimisation process.

Abstract: The invention relates to a method for determining a progressive ophthalmic lens, comprising: - determining a first intermediate value of regression (d1) as the strongest regression that can be applied on the front surface of the lens while keeping a mean sphere value in at least a portion of the lower part of the rear surface of the lens less or equal to a first predetermined value (V1); - determining a second intermediate value of regression (d2) as the strongest regression that can be applied on the front surface of the lens while keeping a mean sphere value in at least a portion of the lower part of the front surface of the lens superior or equal to a second predetermined value (V2); - determining a third intermediate value of regression (d3) as the strongest regression that can be applied on the front surface of the lens while keeping an addition on the rear surface of the lens less or equal to a third predetermined value (V3); - determining a value of regression (d) for the front surface as the maximum value among the first, second and third intermediate values of regression.
