METHOD FOR DETERMINING A VALUE OF A GLOBAL SENSITIVITY PARAMETER OF A SUBJECT, METHODS USING THIS VALUE AND SYSTEM FOR DETERMINING SAID VALUE

摘要

The invention relates to a method for determining a value of a global sensitivity parameter of a subject, said global sensitivity parameter being relative to the sensitivity of said subject to a variation of at least an optical feature of at least an ophthalmic lens placed in front of at least one eye of said subject, comprising the following steps:a) determining (100) a single value of at least a first sensitivity parameter of said subject, relative to the sensitivity of the subject to a variation of a first optical feature of at least a first ophthalmic lens,b) determining (110) a single value of at least a second sensitivity parameter of said subject, relative to the sensitivity of the subject to a variation of a second optical feature of at least a second ophthalmic lens,c) determining (120) said value of the global sensitivity parameter taking into account a combination of said single values of the first and second sensitivity parameters.;It also related to methods using this value and a system for performing this method.
