Abstract:
The present disclosure relates generally to systems and method for testing and determining corrective lens prescription for a patient. In an example embodiment, a method includes using a hand-portable first electronic device, a second electronic device with a computerized screen, and a server to conduct a vision test for a person. The vision test includes determining, an axis prescription, a cylinder prescription, and a sphere prescription for each eye of the person. A corrective lens prescription is provided for the person based, at least in part, on the determined axis, cylinder, and sphere prescription for each eye of the person.

Claim (Index 28):
A computer program for operating a server to enable the administration of a vision test without the use of a refractor lens assembly to determine a corrective lenses prescription for a person using a hand-portable first electronic device and a second electronic device associated with a computerized screen, said computer program causing the server to:\n receive account credentials associated with an account of the person; a. associate one or more of the hand-portable first electronic device or the second electronic device with the account; receive vision information associated with the person, said vision information including a previous corrective lens prescription of the person; enable the person to use the hand-portable first electronic device to interact with the second electronic device via the server; provide one or more computer programs to each of the first electronic device and the second electronic device to cause one or more of the first electronic device or the second electronic device to:\n provide both written and audible instructions to the person, \n perform a calibration step to provide at least one of the server, the hand-portable first electronic device, or the second electronic device with information regarding a property or a parameter of the hand-portable first electronic device, the second electronic device, or the second computerized screen, \n determine an axis prescription, a cylinder prescription, and a sphere prescription for each eye of the person based at least in part on each of (i) data related to inputs from the person in response to figures displayed for the axis prescription, the cylinder prescription, and the sphere prescription, (ii) the previous corrective lens prescription of the person, and (iii) one or more inputs of one or more optometrists or ophthalmologists, and \n cause to be provided to the person the new corrective lens prescription based, at least in part, on the determined axis, sphere, and cylinder prescription for each eye of the person, wherein the determination of the axis prescription for each eye of the person comprises:\n separately for each eye of the person, causing to be displayed on the computerized screen a succession of axis figures, each axis figure comprising a fan chart comprising substantially radial line segments spaced at regular angular intervals, the magnitude of said angular intervals, when expressed in degrees, being a factor of 180, and enabling the person to provide at least one axis input using the hand-portable first electronic device designating an angular direction, if any, in which the radial lines appear most distinct, and \n using the at least one axis input provided in response to each axis figure in the succession, \n wherein determination of the sphere prescription for each eye of the person comprises:\n separately for each eye of the person, causing to be displayed on the computerized screen a succession of one or more sphere figures, wherein the succession comprises figures of varying sizes such that each of the spheres figure in the succession of sphere figures, after a first sphere figure in the succession, has a size equal to or smaller than that of a preceding sphere figure in the succession, \n for each of the sphere figures in the succession, enabling the person to provide at least one sphere input using the hand-portable first electronic device, wherein the at least one sphere input provided in response to the one or more sphere figures pertains to identifying a portion of one of the sphere figures that is different from corresponding portions of the other sphere figures, and \n using information pertaining to the displayed one or more sphere figures, the at least one sphere input, and the distance of the person from the computerized screen, \n wherein determining the cylinder prescription for each eye of the person comprises:\n separately for each eye of the person, using at least one cylinder input of the person in response to a additional axis figure displayed for determination of the cylinder prescription and the previous corrective lens prescription of the person.
