1. A computer-implemented method for testing vision of a human subject, said method comprising the steps of:
- (a) adjusting at least one setting of a display device such that a sequence of graphic objects displayed on said display device conforms to a pre-defined appearance;
(b) displaying said sequence of graphic objects on said display device to perform series of tests of the visual functioning of the human subject;
(c) recording actions of the human subject performed in response to the display of said sequence of graphic objects;
(d) calculating from said recorded actions at least one aspect of the visual functioning of the subject; and
(e) calculating at least one corrective lens prescription for the human subject from at least one of the calculated aspects of the visual functioning of the subject.

Abstract
A method and apparatus are provided for testing the vision of a human subject using a series of eye tests (310). A test setup procedure (312) is run to adjust the settings of a display device (1914) such that graphic objects displayed on the device (1914) conform to a pre-defined appearance. A series of preliminary tests (314), static tests (316) and dynamic tests (318) are displayed on the device (1914), and the responses of the subject are recorded. The tests (310) may be run remotely, for example over the Internet. No lenses are required to run the tests (310).

31. An apparatus for testing vision in a human subject, the apparatus comprising:
-
means for adjusting at least one setting of a computer display such that a sequence of graphic objects displayed on said computer display conforms to a pre-defined appearance; means for displaying said sequence of graphic objects on said computer video display for performing a series of tests of the visual functioning of said human subject; means for recording actions of said human subject performed in response to the display of said sequence of graphic objects; means for calculating from said recorded actions at least one aspect of the visual functioning of said subject; and means for calculating at least one corrective lens prescription for the human subject from at least one of the calculated aspects of the visual functioning of the subject.

32. A computer program element comprising computer program code means to make a computer execute a procedure to:
-
adjust at least one setting of a video display of said computer such that a sequence of graphic objects displayed on said video display conforms to a pre-defined appearance; display said sequence of graphic objects on said video display to perform a series of tests of the visual functioning of said human subject; record actions of said human subject performed in response to the display of said sequence of graphic objects; calculate from said recorded actions at least one aspect of the visual functioning of said subject; and calculate at least one corrective lens prescription for the human subject from at least one of the calculated aspects of the visual functioning of the subject.

33. A computer readable medium, having a program recorded thereon, where the program is configured to make a computer execute a procedure to:
-
adjust at least one setting of a video display of said computer such that a sequence of graphic objects displayed on said video display conforms to a pre-defined appearance; display said sequence of graphic objects on said video display to perform a series of tests of the visual functioning of said human subject; record actions of said human subject performed in response to the display of said sequence of graphic objects; calculate from said recorded actions at least one aspect of the visual functioning of said subject; and calculate at least one corrective lens prescription for the human subject from at least one of the calculated aspects of the visual functioning of the subject.

34. A system for the testing of vision in a human subject, said system comprising:
-
(a) a server having; a first memory for storing an application program and one or more test results from visual testing of a human subject; means for receiving said one or more test results; means for transmitting said application program; means for processing said one or more test results to calculate at least one aspect of the visual functioning of the human subject; and means for calculating at least one corrective lens prescription for the human subject from said at least one aspect of the visual functioning of the subject; and (b) a client computer having; a display device for displaying a sequence of graphic objects to the human subject; means for receiving said application program; means for running said application program to adjust at least one setting of said display device such that said sequence of graphic objects displayed on said display device conforms to a pre-defined appearance; means for recording said one or more test results of the human subject in response to the display of said sequence of graphic objects; and means for transmitting said one or more test results to said server.

35. A method of standardising the appearance of visual objects displayed on a video display, the method comprising the steps of:
-
installing an application program file on a computer; displaying said visual objects on said video display connected to said computer; requesting a person viewing said video display to confirm the size of at least one of said visual objects; requesting the person to confirm whether a specified one of said visual objects is visible; and said application program file utilising the responses of the person to said requests to adjust the relative outputs of the colours used in displaying said visual objects and the relative dimensions of said visual objects.

36. A computer-implemented method for measuring the vision of a human subject, said method comprising the steps of:
-
displaying on a display device a first test to check whether the vision of said subject is within a measurement range of said method; displaying on said display device a second test to determine a required sensitivity of said method; selecting, based on responses of said subject to said first and second tests, further tests to display on said display device to measure an optical power of one or both eyes of said subject;
wherein said further tests are selected from the group consisting of;tests of visual acuity; tests of spherical power; tests of cylindrical power; tests for astigmatism; and tests for near visual acuity; and wherein said subject views said first test, said second test and said further tests without lenses being interposed between said display device and said subject. - View Dependent Claims (37, 38, 39, 40)
