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.

Abstract: A method is disclosed for determination of an ophthalmic lens for a wearer for whom a near-vision and far-vision astigmatism prescription has been made out, the near-vision astigmatism being different from the far-vision astigmatism. The method includes the steps of: choosing a starting lens and defining a current lens equal to the starting lens; optimization, in worn conditions, of the current lens using as a target the astigmatism for which the wearer has been giving a prescription for far vision and the astigmatism for which the wearer has been given a prescription for near vision.

Abstract: The invention relates to a method for determination by optimisation of an ophthalmic lens, taking into account not only the prescription of the wearer for far sight: strength, amplitude and axis of the astigmatism, but also the prescription of the wearer for near sight. Said near sight prescription is measured with binocular vision. The lens is thus defined by optimisation, using the prescription for strength and astigmatism for far sight and near sight as target. According to the invention, variations in astigmatism arising from viewing conditions can be accounted for, objects being generally further away for far sight than for near sight. Account can also be taken of variations in astigmatism caused by physiological deformations of the eye in the rotation thereof on passing from a primary viewing direction to a viewing direction adapted to near sight.
