Abstract | An ophthalmic lens (10) comprises an optical component (1) and a layer (2) placed on a face of the optical component (1a). The layer (2) has a variable refractive index and is structured so that a second order derivative of the index with regard to a linear spatial coordinate along the face of the optical component (1a) is greater than a fixed threshold. The layer (2) makes it possible to alter the optical power and astigmatism of the lens (10) with regard to corresponding values only relative to the optical component (1). In the event that the ophthalmic lens (10) is a progressive lens, the layer (2) makes it possible to change an addition, a length of progression and/or a design of the progressive lens. |
