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;
wherein during the manufacturing data collecting sets of manufacturing data are collected from a plurality of lens manufacturing sides;
wherein the manufacturing data further comprise sets of yield data indicative of at least a yield at each manufacturing side and during the manufacturing information generating the at least one manufacturing information is generated based on the collected yield data; and
a target yield providing, during which at least a target of yield of the optical lens manufacturing process at the second lens manufacturing side is provided and during the manufacturing information generating the at least one manufacturing information is generated based on the target yield.

2. The method according to claim 1 , wherein the first and second lens manufacturing side are the same.

3. The method according to claim 1 , wherein at least part of the manufacturing data collected during the manufacturing data collecting are sensed by a network of sensors at the first manufacturing side.

4. The method according to claim 1 , further comprising a manufacturing information processing during which the manufacturing information is processed to generate an alert and/or a recommendation and/or an activation parameter.

5. The method according to claim 4 , wherein during the manufacturing information generating the at least one manufacturing information is generated using statistical analysis of the collected manufacturing data and allows to generate an alert and/or a recommendation and/or an activation parameter by anticipation.

6. The method according to claim 4 , wherein the manufacturing information processing is realized by using statistical analysis as data mining for pattern detection and/or machine learning and/or artificial intelligence to generate an alert and/or a recommendation and/or an activation parameter by anticipation.

7. The method according to claim 4 , wherein the manufacturing information processing is realized by using machine learning including supervised learning, semi-supervised learning, unsupervised learning, or artificial neural network, association rule learning, hierarchical clustering, cluster analysis, or outlier detection.

8. The method according to claim 1 , wherein the yield is obtained by comparing a quality parameter, or roughness of the lens, aspect of the lens, or satisfaction of the wearer, with a requirement, a standard, or with predetermined metes and bounds.

9. The method according to claim 1 , wherein the yield is a throughput yield measuring ability of the process to produce defect-free units.

10. The method according to claim 1 , wherein the yield is a yield to put which indicates rate of return to an investor.

11. The method according to claim 1 , further comprising an additional data collecting during which additional data provided by an additional side different from the first and second manufacturing side are collected, and wherein during the manufacturing information generating the additional data is considered when generating the at least one manufacturing information.

12. The method according to claim 11 , wherein the additional data is rate of customer satisfaction.
