Abstract: The present invention relates to an ophthalmic lens, having, on its surface, a colorless or yellow, central first zone and at least one peripheral second zone, selectively transmitting visible light having a wavelength of less than 570 nm.

Abstract: The present invention relates to an ophthalmic lens comprising, on its surface, a first central yellow zone preferentially absorbing the blue light of the visible spectrum, a second peripheral zone preferentially absorbing light having wavelengths of less than 600 nm, and preferentially a third zone which is colourless, grey, or brown in the lower part of the lens.

Abstract: A method makes a customised progressive ophthalmic lens intended for an identified wearer that includes measurements of the inclination of the wearer's head. These measures are made when the wearer performs visual tasks in far-vision conditions, by consecutively looking horizontally, then towards the ground. A variation of the optical power of the progressive lens, below a reference direction for the far vision, is adjusted on the basis of the measure results. The habituation period of the wearer to the progressive lens can thus be reduced.

Abstract: A progressive lens for ophthalmic spectacles has an additional zone for intermediate vision. This additional zone is located beneath a near-vision zone. It enables objects located at a distance of between 1.0 and 1.5 meters, in a direction inclined at about 35 degrees to a line of sight passing through a cross mark (CM) on the lens, to be seen clearly. To achieve this, the optical power progression between a far-vision point (FV) and a near-vision point (NV) of said lens has a power-increase threshold which is located approximately at the cross mark.

Abstract: The present invention relates to an ophtalmic lens, having, on its surface, a colourless or yellow, central first zone and at least one peripheral second zone, selectively transmitting visible light having a wavelength of less than 570 nm.

Abstract: The invention relates to an ophthalmic lens comprising, on its surface, a coloured zone the extent of which is limited to the zone of the lens explored by the eye of the user when reading, the remainder of the lens being colourless.

Abstract: The invention relates to an ophtalmic lens comprising, on its surface, a first central zone preferentially transmitting the long wavelengths of the visible spectrum, and a second peripheral zone preferentially transmitting the short wavelengths of the visible spectrum.

Abstract: The invention concerns a transparent and polarizing viewing element (2) divided into several zones (2a, 2b). At least one of the zones (2a) is associated with a light polarizing filter. The light passing through the optical surface is affected differently for two of said zones (2a, 2b) depending on the polarizing direction of said light. The polarizing filter is obliquely oriented relative to a horizontal direction (H) in the operational position of the element (2; 5), with an angle between the filter orientation and said horizontal direction of 90 degrees and of 0 degree.

Abstract: The invention relates to a method for producing a polarising ophthalmic lens adapted to the eye/head behaviour of the wearer thereof and to said lens. The inventive ophthalmic lens comprises several areas associated to differently oriented polarising filters. The size and position of at least certain areas are determined according to the lens wearer's eye/head behaviour.

Abstract: A transparent and polarizing vision element (2) divided into several areas. At least two of said areas are associated with a luminous polarization filter. The light flowing through the element is allocated differently for two the areas according to a direction of polarization of the light. At least one polarization filter is oriented vertically, and at least one polarization filter is oriented horizontally in relation to the usual position of the element.
