Abstract: A method and apparatus are provided for optical manufacturing laboratories (OMLs) obtaining a plurality of performance indictors (PIs). The PIs are published or otherwise distributed among one or more participants (e.g., one or more ECPs and/or an administrative team of the OMLs). Logic blocks are generated for respective manufacturing orders to express priorities of the requirements/preferences of the respective orders. A combination of the logic blocks together with the plurality of PIs are applied as inputs to the selection rules (e.g., routing logic), which then output rankings of the OMLs in accordance with the priorities of the respective orders. The orders are then routed to an optimal combination of the OMLs based on the results from the selection rules.

Abstract: An optical device that includes an active programmable lens including a first zone configured to provide to a wearer, in standard wearing conditions, a correction of at least one eye based on a prescription, according to a first adjustable dioptric function. The optical device provides first vision distance data corresponding to a first distance between a first object in the environment of the wearer and the active programmable lens, stores vision distance data and at least two predetermined optical power states, each predetermined optical power state corresponding to an optical power value relative to a range of vision distance, and controls the first adjustable dioptric function of the first zone of the active programmable lens by adjusting the first adjustable dioptric function of the first zone of the active programmable lens according to an optical power state based on the provided first vision distance data.
