Systems and methods for providing high resolution corrective ophthalmic lenses

Abstract

Described are 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.

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Application No. 61 / 992,000, filed May 12, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The described invention relates to systems and methods for providing high resolution corrective ophthalmic lenses. These systems and methods include taking measurements and providing corrective ophthalmic lenses based on the identification of certain measurements. Background technique [0004] Correcting the eye's vision by non-surgical means involves measuring refractive error using gradients in steps of 1 / 4 or 0.25 diopters. Such gradients do not take into account the accuracy available with existing digital equipment. Therefore, there remains a need to provide a gradient better than 0.25 diopters. However, for many individuals, particularly individuals with reduced sensitivity to higher levels of gradation, such higher...

Problems solved by technology

However, for many individuals, especially those with reduced sensitivity to higher levels of gradation, such higher levels of gradation are not very noticeable when provided on the surface of an ophthalmic lens used to correct eye vision

Correction at higher resolution (resolution of less than 0.25 diopters) may not be conscious or even perceived in these individuals who are attenuated or unable to perceive even higher level gradations
