A display managing method for managing the display of an image to a user of an optical system comprising at least a see-through displaying device arranged and configured to display the image towards an eye of the user and an optical lens designed to be placed in front of the eye of the user and having an optical function, the method comprises: - an optical function data providing step (S2), during which optical function data relating to the optical function of the optical lens are provided; - a gazing direction determining step (S6) during which the gazing direction of the eye of the user is determined; - a zone of interest identification step (S8), during which at least one zone of interest of the optical lens is identified based on the optical function data relating to the optical function of the optical lens, and - a display parameter determining step (S4), during which a value of at least one display parameter is determined based at least on the optical function data, on the at least one zone of interest and on the determined gazing direction. wherein the optical function data comprise at least dioptric function data relating to a dioptric function based at least on an ophthalmic correction adapted to the user, wherein the at least one display parameter comprises the position of the image and/or angular extent of the image and/or the projection distance of the image, wherein the at least zone of interest comprises a near distance vision zone adapted for near distance vision and/or a far distance vision zone adapted for far distance vision and/or an intermediate distance vision zone adapted for intermediate distance vision and/or a distortion zone and/or an aberration zone, wherein the see-through displaying device comprises at least a tracking component adapted to determine the gazing direction of at least the eye of the user towards which the image is displayed and wherein the method further comprises - an optical function data providing step (S2), during which optical function data relating to the optical function of the optical lens are provided; - a gazing direction determining step (S6) during which the gazing direction of the eye of the user is determined; - a zone of interest identification step (S8), during which at least one zone of interest of the optical lens is identified based on the optical function data relating to the optical function of the optical lens, and - a display parameter determining step (S4), during which a value of at least one display parameter is determined based at least on the optical function data, on the at least one zone of interest and on the determined gazing direction. wherein the optical function data comprise at least dioptric function data relating to a dioptric function based at least on an ophthalmic correction adapted to the user, wherein the at least one display parameter comprises the position of the image and/or angular extent of the image and/or the projection distance of the image, wherein the at least zone of interest comprises a near distance vision zone adapted for near distance vision and/or a far distance vision zone adapted for far distance vision and/or an intermediate distance vision zone adapted for intermediate distance vision and/or a distortion zone and/or an aberration zone, wherein the see-through displaying device comprises at least a tracking component adapted to determine the gazing direction of at least the eye of the user towards which the image is displayed and wherein the method further comprises <EOS>
