Disclosed is a method for deducing geometrical defects of an optical article turning machine, including a defect value deducing step, during which at least one geometrical defect value is deduced based at least on an indicative information of an optical and/or geometrical data related to an optical and/or geometrical characteristic of a checking piece (10).

A method of processing an order request for an ophthalmic lens to be manufactured by a manufacturing device includes the following steps: receiving an order request including at least information related to an ophthalmic wearer's prescription by a first processing device; processing the order request by the first processing device on the basis of predetermined processing rules so as to obtain manufacturing parameters to be applied to the manufacturing device so as to manufacture the ophthalmic lens according to the information included in the order request; sending and storing the manufacturing parameters identified as requiring a further modification to a storing device and sending the other manufacturing parameters to the manufacturing device; modifying the stored manufacturing parameters by a second processing device and sending the modified manufacturing parameters to the manufacturing device.

A method for monitoring an optical lens manufacturing process at a first lens manufacturing side, the method including: a manufacturing data collecting, during which sets of manufacturing data indicative of at least a manufacturing process parameter and/or a manufacturing device parameters and/or an operator parameter and/or an environment parameter at the first lens manufacturing side are collected; a manufacturing information generating, during which at least one manufacturing information indicative of at least a manufacturing process parameter and/or a manufacturing device parameters and/or an operator parameter and/or an environment parameter at a second lens manufacturing side is generated based on the collected manufacturing data.

A lens assembling device includes a collimator, a sensor, a feedback control platform located between the collimator and the sensor, a lens transfer component, and a processor electrically or signal connected to the feedback control platform, the sensor, and the lens transfer component, respectively. A method for assembling lenses by the lens assembling device is also disclosed.

This disclosure includes methods and systems for producing ophthalmic lenses. Some methods include identifying a plurality of zones within a spatial representation of a lens blank, selecting, for each of the zones, one or more parameters for producing the lens, and producing the lens by removing material from the lens blank according to the one or more parameters of each of the zones.

A method and apparatus for blocking an unfinished optical lens member on a blocker for manufacturing an optical lens from the unfinished optical lens member, the latter being provided with a finished surface having a first reference frame, the blocker having a second reference frame, includes: placing the unfinished optical lens member on the blocker; measuring the relative positioning of the first reference frame of the finished surface of the placed unfinished lens member with respect to the positioning of the second reference frame of the blocker; comparing the measured relative positioning with a predetermined relative positioning to determine a relative positioning shift; moving at least the blocker and/or the lens member to change the relative positioning of the first reference frame with respect to the second reference frame to compensate for the relative positioning shift; and blocking the unfinished lens member on the blocker at the changed relative positioning.
