1. A method for providing a head mounted optical system adapted to a wearer, the method comprising:
an optical system providing step, during which an optical system is provided, the optical system being an electro-optical system with a switchable function that enables at least part of an active function of the system to be controlled by means of an electrical stimulus;
a wearer data providing step, during which wearer data comprising at least the wearer's prescription is provided;
an encapsulating step, during which the optical system is at least partly encapsulated in a transparent capsule;
an optical system data providing step, during which optical system data representing at least a shape of faces of the optical system prior to the encapsulation step and an optical index of the optical system is provided;
a capsule data providing step, during which capsule data representing at least an optical index of the transparent capsule and a shape of at least one of a first face and a second face of the capsule is provided;
an optical function determining step, during which an optical function to be provided to the wearer is determined according to the wearer data and the system data;
a surface data determining step, during which surface data representing the surface of at least one face to be customized of the capsule is determined according to the optical function and the capsule data; and
a customizing step, during which at least one face of the transparent capsule is customized according to the surface data;
wherein the optical system is at least partly encapsulated in a transparent capsule by stacking in close contact the optical system with at least one substrate of the transparent capsule and made integral with an adhesive.
