Abstract: The present invention relates to a method for providing a model assessing a quantitative expected global quality level of an ophtalmic lens, said lens having given lens and environment parameters, and being produced by a digital lens manufacturing process. A method for real-time in-line quality audit of the freeform production line is provided, by means of a process quality score, built as the result of the normalization of the computed global quality level based on the expected value of manufactured lenses obtained by normal production.

Abstract: An apparatus for clamping and handling an ophthalmic lens (A) in one or a plurality of stations throughout a manufacturing process, comprising: a main actuator (5); a loading platform (3) on which the lens is laid down with its concave surface downwards; a grip composed of two arms (1, 2) for clamping the lens on its edge, a first arm (1) being bound to said main actuator (5) and a second arm (2) being guided so that to allow for a movement parallel to the main actuator displacement; a first means for attracting the second arm (2) towards the first arm (1) so that to close the grip onto the lens edge; a second means (8) for blocking the second arm (2) at a fixed position when the first arm (1) is moved to a rest position so that to open the grip; holding fingers (6) mounted on at least one of the first arm (1) and the second arm (2) and partly sliding along parallel grooves (4) machined in said platform (3), said grooves (4) being also parallel to the actuator displacement.
