Disclosed is a method for testing the feasibility of a pair of spectacles, the pair of spectacles comprising an identified spectacle frame. The method includes steps of: a) acquiring a range of values of at least one first parameter relating to a spectacle wearer, in all of which range it is desired to ensure the feasibility of the pair of spectacles, b) acquiring a range of values of at least one second parameter that relates to a spectacle wearer and that is different from each first parameter, in all of which range it is desired to ensure the feasibility of the pair of spectacles, c) confirming, for a characteristic number of values of each second parameter, that the pair of spectacles is feasible whatever the value of each first parameter comprised in its range.
