Problems solved by technology

It is a lengthy and expensive process that requires a visit to a clinician as well as a multi-step test with specialized equipment to receive corrective lenses
[0005] Although attempts have been made to simplify this process, there are serious flaws in these methods that lead to limited use, measurement errors, and feasibility issues

Abstract

Methods, systems, and devices are provided for measuring eye refraction without a lens, and more particularly, for measuring eye refraction with a mobile device application. An exemplary method includes measuring a distance between a patient and a mobile device, presenting to the patient one or more visual targets sized and shaped to represent perfect vision such as by using Vernier targets or grating targets, instructing the patient to indicate whether the patient can accurately read the visual targets and, if not, to move closer to the mobile device until the patient can accurately read thevisual targets, calculating a vision prescription for the patient based on the visual targets and a final distance between the patient and the mobile device, and displaying the vision prescription forthe patient.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 634,061, entitled "Measuring Eye Refraction," filed February 22, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to measuring eye refraction without the use of lenses, and more particularly to mobile device applications for eye refraction measurement. Background technique [0004] In general, measuring eye refraction is a lengthy and relatively complex process that requires specialized equipment and specialized training. To obtain a prescription for corrective lenses (Rx), a patient typically must see an optometrist or other specialized clinician to have the eye's refraction measured. This test accurately determines the prescription for eyeglasses that the patient needs. Traditional methods of refraction measurement require the clinician to place the patient away from a visual s...
