摘要： 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.

摘要： Systems and methods for providing identification factors for an individual wearer. Some or all of the identification factors when within a predetermined value provide a prescription and corrective ophthalmic lenses for a selected individual wearer, the corrective ophthalmic lens having at least one correction that is to the nearest 0.20 diopter, or is in a range between about the nearest 0.01 diopter and about the nearest 0.20 diopter. The prescription and corrective ophthalmic lenses are obtained by at least first analysis performed with a first instrument, a second analysis performed with a second instrument, and a third analysis performed with a third instrument, in which each instrument is different, and each analysis is different.
