Abstract

The invention relates to a method for measuring at least one geometrico-morphological parameter of a subject (2) wearing an eyewear (3) in order to fit an ophthalmic lens in said eyewear. The method comprises the following steps:- placing the subject wearing the eyewear in a natural posture while looking at a visual symbol (17) among a plurality of visual symbols (9) on a visual target (6),- placing a double-sided image capture apparatus (5) between the subject and the visual target, with a first image capture device (10) facing the subject, a second image capture device (11) facing the visual target,- obtaining images of both the subject and visual target thanks to the double-sided image capture apparatus (5),- determining at least one first point (18) and at least one second point (19) from each of the images,- identifying the visual symbol,- determining the at least one geometrico-morphological parameter using the at least one first and second points and the identification of the visual symbol.The invention also relates to an associated system and a fitting method.
