<p>The invention concerns a method for making an ophthalmic lens surface. It comprises steps which consist in: a) machining the surface by material removal by moving a cutting tool along a continuous path to produce grooves, two adjacent grooves being spaced by a constant pitch ranging between 0.01 and 3 mm, and b) smoothing the machined surface by moving a smoothing tool along a continuous path consisting of runs, two adjacent runs being spaced by a constant pitch ranging between 0.2 and 3 mm, to produce a pass band filtering for the undulations of said surface between a low frequency corresponding to a surface envelope to be achieved and a high frequency corresponding to a base roughness.</p> |
