Computerized refraction and astigmatism determination

摘要

The present disclosure relates generally to a system and method for determining the refractive error of a patient, more particularly determining the patient's refractive error by using a computerized screen, and providing the patient with a prescription for the patient's preferred type of corrective lenses. The system and method do not require the trip or expense of a doctor visit, and are optimized for convenience and cost effectiveness. In a general embodiment, the present disclosure provides a method for determining a corrective lenses prescription of a patient. The method includes, separately, for each eye of the patient, determining the astigmatism prescription of the patient via a computerized screen, and determining the power of the corrective lenses prescription of the patient via the computerized screen.

主权项

1. A method for determining a corrective lenses prescription for a patient comprising, separately, for each eye of the patient:
determining an astigmatism prescription for the patient via a computerized screen and without the use of a refractor lens assembly, wherein determining the astigmatism prescription for the patient comprises testing for a cylinder component by sequentially presenting at least two cylinder diagrams to the patient via the computerized screen and enabling the patient to select at least one input per cylinder diagram, wherein the at least one input per cylinder diagram corresponds to a cylinder measurement used to determine the corrective lenses prescription for the patient.
