A method, implemented by computer means, for ordering an optical equipment comprising at least a spectacle frame suitable for a wearer, the method comprising: - a wearer data providing step during which wearer data relative to a wearer parameter are provided, - an optical equipment data providing step during which optical equipment data relative to at least the spectacle frame of an optical equipment selected by the wearer and weight data representative of the weight distribution in the spectacle frame of the optical equipment selected by the wearer are provided, - a mounting data determining step during which mounting data representative of the spectacle frame being mounted on the wearer's head are determined by taking into account at least said wearer's data and said optical equipment data, the mounting data being further based on dynamic data representative of the behavior of the optical equipment when mounted on the wearer's head having a dynamic motion, - a deformation data determining step, during which deformation data representative of a deformation of the spectacle frame part of the optical equipment selected by the wearer are determined based on the wearer data and the mounting data, - a display step during which the mounting data are displayed in a visually understandable mode, - a wearer's opinion providing step during which the wearer's opinion concerning the mounting data is provided, - a mounting data modifying step during which the mounting data are modified based on information relating to the wearer's opinion, wherein during the mounting data modifying step the mounting data are modified taking into account the deformation data, wherein the mounting data determining step, display step, wearer's opinion providing step and mounting data modifying step are repeated up to the wearer's satisfaction so as to obtain final mounting data. - a wearer data providing step during which wearer data relative to a wearer parameter are provided, - an optical equipment data providing step during which optical equipment data relative to at least the spectacle frame of an optical equipment selected by the wearer and weight data representative of the weight distribution in the spectacle frame of the optical equipment selected by the wearer are provided, - a mounting data determining step during which mounting data representative of the spectacle frame being mounted on the wearer's head are determined by taking into account at least said wearer's data and said optical equipment data, the mounting data being further based on dynamic data representative of the behavior of the optical equipment when mounted on the wearer's head having a dynamic motion, - a deformation data determining step, during which deformation data representative of a deformation of the spectacle frame part of the optical equipment selected by the wearer are determined based on the wearer data and the mounting data, - a display step during which the mounting data are displayed in a visually understandable mode, - a wearer's opinion providing step during which the wearer's opinion concerning the mounting data is provided, - a mounting data modifying step during which the mounting data are modified based on information relating to the wearer's opinion, <EOS>
