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 20):
A method for determining a corrective lenses prescription for a person by performing a vision test without the use of a refractor lens assembly using a hand-portable first electronic device, a second electronic device associated with a computerized screen, and a server, the method comprising:\n receiving, in the server, account credentials associated with the person; receiving, in the server, vision information associated with the person, said vision information including at least one of a previous corrective lens prescription of the person, a date of birth of the person, or an age of the person; enabling the person to use the hand-portable first electronic device to interact with the second electronic device via the server; providing both written and audible instructions to the person using one or more of the hand-portable first electronic device and the second electronic device; performing a calibration step to provide any 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 computerized screen; specifying, via at least one of the hand-portable first electronic device or the second electronic device, a distance for the person to be positioned away from the computerized screen; receiving, in the server, data corresponding to inputs from the person submitted using the hand-portable first electronic device in response to the vision test; determining 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) said data, (ii) the previous corrective lens prescription of the person, and (iii) one or more inputs of one or more optometrists or ophthalmologists; and providing to the person a new corrective lens prescription based, at least in part, on the determined axis, cylinder, and sphere prescription for each eye of the person, wherein a first set of tests presented is used to determine the axis prescription for each eye of the person, and determining the axis prescription for each eye of the person comprises:\n separately for each eye of the person, displaying on the computerized screen a succession of one or more 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, \n displaying the one or more axis figures in the succession at a different angular orientation than one or more other axis figures in the succession, and \n using the at least one axis input provided in response to each axis figure in the succession, \n wherein determining the sphere prescription for each eye of the person comprises:\n separately for each eye of the person, displaying on the computerized screen a succession of one or more sphere figures, wherein the succession comprises figures of varying sizes where 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 second axis figure displayed for the cylinder prescription determination and the previous corrective lens prescription of the person, \n displaying on the computerized screen one or more additional figures comprising shapes having one or more spaces such that portions of the one or more additional figures appear to touch across the one or more spaces when viewed using an astigmatic eye, and enabling the person to provide at least one additional input using the hand-portable first electronic device, \n using the at least one additional input, the distance of the person from the computerized screen, and the at least one sphere input made by the person in response to the one or more sphere figures, the cylinder input made by the person in response to the axis figure, the determined sphere prescription, and the determined axis prescription, and \n wherein determining the new corrective lens prescription further comprises: \n displaying on the computerized screen a diagram comprising a red-colored block and a green-colored block, each block comprising a block figure, \n requesting one or more first block inputs from the person to indicate whether one of the block figures appears more distinct than another one of the block figures and, if so, requesting one or more second block inputs from the person to indicate which of the block figures appear more distinct than the other of the block figures, and \n using at least one of the one or more first block inputs or second block inputs made by the person in response to said diagram to determine if the he new corrective lens prescription is over-corrected or under-corrected, \n wherein the inputs provided by the person using the hand-portable first electronic device impact a progression of the vision test as displayed on the computerized screen through interaction of the hand-portable first electronic device with the second electronic device via the server, wherein no ophthalmologist or optometrist is required to contemporaneously monitor the vision test.
