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

Embodiment Construction

[0027] Described herein are a plurality of identification factors for determining an individual wearer and a method for selecting an individual wearer. Such as figure 1 As depicted, multiple identification factors are identified, and individual wearers are selected. At block 110, a first identification factor is identified. At block 115, it is then determined that the first visual identity is equal to or within a predetermined value. If the first identification factor is not equal to or not within a predetermined value, the individual wearer is not selected, and an alternative arrangement for the individual wearer is provided at block 120, such as an established any known alternative steps. In some embodiments, at block 120, an individual wearer may still be evaluated and formulated with an advanced corrective ophthalmic lens as described below.

[0028] If at block 125 the first identification factor is equal to or within a predetermined value, then at block 130 a second ...

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.

Description

[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...
