Abstract: The invention relates to a method for uncoupling the support and removing a protective film from lenses during production. The method consists of: a phase comprising the weakening of the layer (5) of fluxing material, specific to a matching support (4), with the application of a hot fluid in order to soften same; the lateral projection of a jet (7) of pressurized liquid onto the support (4) in order to detach said support; the lateral projection of an orientable pressurized jet (8) onto the edge of the lens (1) in order to raise the protective sheet (3) to be found on the front face of the lens and to detach same fully from the lens; and the draining of the lens (1) in order for same to be delivered to an outlet tray.
