Abstract: Disclosed is a semi-finished lens that includes a blank formed in a first material having a first hardness, the blank having an outline, a first face and a second face configured to be surfaced so as to constitute a first optical face of the ophthalmic lens, and a top layer formed in a second material having a second hardness greater than the first hardness, the top layer having an outline, a first face and a second face, the second face of the top layer being arranged on the first face of the blank. The outline of the top layer is equal to or included in the outline of the blank, and satisfies to a predetermined dimensional selection criterion involving the final outline of the ophthalmic lens.

Abstract: A functionalized layered structure (2, 3, 20, 30) includes: a first element that is a first single-layer or multi-layer functional film (2A, 4); at least one second element selected among a second functional film (2B) and a basic optical element (200, 300); at least one first pressure-sensitive adhesive layer (5A, 5B, 5) placed in contact with at least one surface of the first element and at least one surface of the second element. The surfaces of the first and second element, which are intended for being placed in contact with the adhesive layer, are subjected to a surface treatment prior to being placed in contact, such that the decrease between the peel force when dry and the peel force when wet is no higher than at least 35%, inclusive.
