    Abstract: The present disclosure relates to a method and device for evaluating a fit of visual equipment. In an embodiment, the method (105) includes receiving (110) an image(s) of a face of a user, identifying (115) a subset of eyeglasses from a database that satisfy a preliminary fit threshold, determining (120) an eyeglass rim plane of a candidate eyeglass, determining (125) an eyeglass pads plane of the candidate eyeglass, generating (130) at least one 2D profile of a nose of the user, generating (140) at least one 2D profile of a nasal section of a frame of the candidate eyeglass, virtually docking (150) the candidate eyeglass on the nose of the face of the user, calculating (170), when the virtually docked candidate eyeglass satisfies a secondary fit threshold, a final fit of the virtually docked candidate eyeglass, the final fit being defined by at least one of a comfort criterion and/or an aesthetic criterion.
