Abstract
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.
