Abstract: The invention relates to a method for decorating an ophthalmic article. The method contains a step of providing an ophthalmic article having a substrate with a first outer surface intended to be oriented towards the field of view of a user. The first outer surface has at least one decoration zone outside the central vision zone of the ophthalmic article and has topographic structures of at least one dimension of length greater than or equal to 1 mm for forming a decorative pattern. The method further contains a step of depositing thin layers on the first outer surface to form an interferometric mirror on top of the first outer surface. The thin layers have a refractive index different from the refractive index of the substrate.

Abstract: A process for automatically gluing a photochromic lens, includes: supplying an adhesive comprising photochromic molecules; supplying an external lens; supplying a polarizing film from a reel; forming the polarizing film on a spherical mold; applying a first portion of the adhesive to the polarizing film positioned on the spherical mold; compressing the polarizing film and the external lens, while measuring a thickness of the first portion of the adhesive therebetween; supplying an internal lens; applying a second portion of the adhesive to the internal lens; compressing the internal lens and the external lens having the polarizing film formed thereon, while measuring a thickness of the second portion of the adhesive therebetween using a measuring device; stopping the compression of the internal lens and the external lens; cutting excess polarizing film; and catalyzing the adhesive to form the glued photochromic lens.

Abstract: The present invention concerns a method for making a thin lens and thin lens (1), said method being characterized in providing the following subsequent steps: a) taking a lens comprising a first optical layer (2), having a first surface (21) and a second surface (22) opposite to the first (21), a second optical layer (3), having a first surface (32) and a second surface (31) opposite to the first (32), and a third layer (4) interposed between said first (2) and second (3) optical layers in correspondence of the respective second surfaces (22, 31), said layers (2, 3, 4) being integrally coupled among each other; b) working the first surface (32; 21) of one (3; 2) of said optical layers (2, 3) for reducing its thickness. Furthermore, the present invention relates to a thin lens (1).
