A method for increasing quality of manufactured optical lenses at a second lens manufacturing side, the method comprising: - a manufacturing data collecting step (S1), during which sets of manufacturing data are collected at a first lens manufacturing side different from the second lens manufacturing side wherein the sets of manufacturing data are indicative of at least a manufacturing process parameter and/or a manufacturing device parameters and/or measuring device parameter and/or an operator parameter and/or an environment parameter at the first lens manufacturing side, - a manufacturing information generating step (S2), step- during which at least one manufacturing information is generated at the second lens manufacturing side based on the collected sets of manufacturing data, characterized in that the manufacturing data further comprise sets of yield data indicative of at least a yield at the first lens manufacturing side and, during the manufacturing information generating step (s2) the at least one manufacturing information is generated based on the collected sets of yield data, the method further comprises a target yield providing step (S11), during which at least a target of yield of an optical lens manufacturing process at the second lens manufacturing side is provided and, during the manufacturing information generating step (S2), the at least one manufacturing information is generated based on the target yield, and the at least one manufacturing information is an alert or a suggestion of using a new service or optical function more adapted to the optical lens manufacturing process at the second lens manufacturing side. - a manufacturing data collecting step (S1), during which sets of manufacturing data are collected at a first lens manufacturing side different from the second lens manufacturing side wherein the sets of manufacturing data are indicative of at least a manufacturing process parameter and/or a manufacturing device parameters and/or measuring device parameter and/or an operator parameter and/or an environment parameter at the first lens manufacturing side, - a manufacturing information generating step (S2), step- during which at least one manufacturing information is generated at the second lens manufacturing side based on the collected sets of manufacturing data, characterized in that the manufacturing data further comprise sets of yield data indicative of at least a yield at the first lens manufacturing side and, during the manufacturing information generating step (s2) the at least one manufacturing information is generated based on the collected sets of yield data, the method further comprises a target yield providing step (S11), during which at least a target of yield of an optical lens manufacturing process at the second lens manufacturing side is provided and, during the manufacturing information generating step (S2), the at least one manufacturing information is generated based on the target yield, and the at least one manufacturing information is an alert or a suggestion of using a new service or optical function more adapted to the optical lens manufacturing process at the second lens manufacturing side. <EOS>
