Abstract:
A method of testing applicable to the provision of a vision aid having colorimetric parameters, the method comprising the steps of:a. providing a vision aid having a chosen value of colorimetric parameters; b. assessing a visual benefit provided by said vision aid, said step of assessing the visual benefit provided by said vision aid comprising the steps of: i. carrying out an optical test in which said vision aid is used optically by said patient to identify a patient response to said test; ii. observing said patient response and deriving quantitative data representing said visual benefit to that particular patient; and iii. interpreting said quantitative data to identify a value of said colorimetric parameters of said vision aid which improves said benefit for said particular patient; and c. determining whether a different vision aid having a differing chosen value of said colorimetric parameters would produce a better result.
