Abstract: The smoothing implement for optical lenses has a support (11) with an annular recess (15) to receive the smoothing tool (12) which is mounted by a smaller recess (16) in the floor of the main recess. The smoothing tool projects beyond the mounting. The implement has an elastic hub and projecting faces on the edges facing the smoothing tool to form an outlet orifice.

Abstract: This tool includes: a rigid support (104) having a transverse end surface (113); an elastically compressible interface that is pressed against and covers the end surface; a flexible pad adapted to be pressed against the optical surface, itself pressed against and covering the interface on the opposite side of and in line with the end surface (113); spring return element (115) connecting the support (104) to a peripheral portion of the flexible pad situated transversely beyond the end surface (113); and a flexible flange (131) that is part of a base (130) to which the rigid support (104), which is surrounded by the flange (131), also belongs.

Abstract: Two stage manufacturing process for prescribed ophthalmic lenses comprises a first cutting tool trajectory followed by a milling tool whose trajectories are controlled by a numerical control unit. Manufacturing process of a prescribed ophthalmic lens surface, comprising the following stages: (a) machining of the surface by moving a cutting tool in a continuous surface envelope trajectory, to form furrows, where two adjacent furrows are consistently 0,01 and 3 mm apart, in order to obtain a surface with mean arithmetic roughness Ra = 0.1 to 0.7 mu m; and (b) smoothing the machined surface using a smoothing tool in a continuous surface envelope trajectory to produce two adjacent streams 0.2 to 3 mm apart, in order to filter the surface envelope undulation between a low frequency corresponding to the envelope and a high frequency corresponding to a basic roughness. This provides a smoothed surface having a mean arithmetic roughness Ra lower than 0,1 mu m. Independent claims are also included for: (i) a digitally controlled machine (Figure 6) comprising a lens support (40) capable of translation and rotation on a vertical axis and a milling tool (10) capable of translation on a horizontal axis, inclinable with reference to a vertical axis and able to rotate on a vertical axis, the translatory (Z) and rotation (R1)) movement of the support (40 )and the translation movements (X) and tilt (B) of the tool being controlled simultaneously by the numerical control unit, the rotation(R2) of the milling tool is also controlled by the control unit; (ii) equipment to provide the surface finish comprising (see Fig 9) a support 1001 in which the lens can be place and rotated and an arm (1003) carrying a nozzle (1002) which provides resin at a low pressure and can be moved vertically and horizontally with respect to the support (1001).

Abstract: A method wherein a layer (16) of a material (17) is applied to the surface of a glass object (10) with a view to etching the glass object (10), and a laser beam (18) is caused to interfere with said material. The material (17) making up said layer (16) is selected for its ability to react with the glass and, e.g. be diffused therein. The method is particularly suitable for marking moulds for ophthalmic lenses.

Abstract: The present invention relates to a method for transforming an initial progressive ophthalmic surface which has to be manufactured by a manufacturing method the transformation method comprising: • a step of selecting a manufacturing method intended to be implemented in which said manufacturing method introduces a reproducible surface defect • a step of selecting a predictive model of said reproducible surface defect • a step of selecting an initial progressive ophthalmic surface S intended to be manufactured • a step of determining (S1) during which there is determined by means of said predictive model a surface defect value D which would be introduced if the initial progressive ophthalmic surface S were produced by said manufacturing method • a transformation step (S2) during which said initial progressive ophthalmic surface S is transformed into a transformed progressive ophthalmic surface S* by compensating the defect value D determined during the step (S1) such that the subsequent manufacture of the transformed ophthalmic surface S* by said manufacturing method makes it possible to obtain a progressive ophthalmic surface which substantially conforms to the initial progressive ophthalmic surface S.
