COMPUTERIZED REFRACTION PRESCRIPTION DETERMINATION WITH SPHERE CALCULATION

摘要

The present disclosure relates generally to a system and method for determining the refractive error of a person, more particularly determining the person's refractive error by using a computerized screen, and providing the person with a prescription for the person'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 for a person. The method includes, separately, for each eye of the person, determining the sphere prescription for the person via a computerized screen and without the use of a refractor lens assembly. Determining the sphere prescription is done, in part, by displaying a sphere figure to the person via the computerized screen and enabling the person to select at least one input, where the input corresponds to a sphere measurement.
