• displaying one or more of the axis figures in the succession at a different angular orientation than one or more of the other axis figures in the succession, and
• using at least one of the at least one axis figure input provided in response to each axis figure in the succession,
• wherein determining the sphere prescription for each eye of the person comprises:
• 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 one or more sphere figures 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,
• for each of the sphere figures in the succession, enabling the person to provide at least one sphere figure input using the hand-portable first electronic device, wherein the at least one sphere figure 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 the other portions of that sphere figure, and
• using information pertaining to the displayed one or more sphere figures, at least one of the at least one sphere figure input, and the distance of the person from the computerized screen,
• wherein determining the cylinder prescription for each eye of the person comprises:
• separately for each eye of the person, using at least one of the at least one axis figure input of the person and the previous corrective lens prescription of the person,
• displaying on the computerized screen one or more figures comprising shapes having one or more spaces such that portions of the displayed figure may appear to touch across the one or more spaces when viewed using an astigmatic eye of the person, and enabling the person to provide at least one input related to the displayed figure using the hand-portable first electronic device,
• using at least one of the at least one input related to the displayed one or more figures, the distance of the person from the computerized screen, and at least one of the at least one axis figure input, the determined sphere prescription, or the determined axis prescription, and
• wherein determining the corrective lens prescription further comprises:
• separately for each eye of the person, displaying on the computerized screen a diagram comprising a red-colored block figure and a green-colored block figure, and enabling the person to provide one or more block figure inputs identifying whether one figure appears more distinct than the other, and if so which one, and
• using at least one of the one or more block figure inputs made by the person in response to said diagram to determine at least one of whether (a) the person's prescription is over-corrected or under-corrected, or (b) the person is myopic or hyperopic,
• wherein at least two selected from the group of:
• the one or more axis figures, the one or more sphere figures, and the one or more figures comprising shapes having one or more spaces are the same figure,
• wherein the inputs provided by the person using the hand-portable first electronic device cause a progression of the vision test as displayed on the computerized screen, and
• wherein no ophthalmologist or optometrist is required to contemporaneously monitor the vision test.

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:

• receive account credentials associated with an account of the person;
• associate at least one of the hand-portable first electronic device or the second electronic device with the account;
