| 20080252846 | Polarizing Ophthalmic Lens Adapted to a Wearer's Eye/Head Behavior - 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. | 10-16-2008 |
| 20100053550 | MULTI-TINT COLOURED OPHTALMIC LENSES - 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. | 03-04-2010 |
| 20100060850 | COLOURED OPHTHALMIC LENSES FOR PEOPLE WITH DYSLEXIA - 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. | 03-11-2010 |
| 20100091240 | MULTITINT OPHTHALMIC LENSES FOR THE SHORTSIGHTED - 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. | 04-15-2010 |
| 20100283963 | PROGRESSIVE LENS FOR OPHTHALMIC SPECTACLES, HAVING AN ADDITIONAL ZONE FOR INTERMEDIATE VISION - 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. | 11-11-2010 |
| 20110128496 | PRODUCTION OF CUSTOMIZED PROGRESSIVE OPHTHALMIC LENS - 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. | 06-02-2011 |
| 20110141434 | MULTI-TINT OPHTHALMIC LENSES FOR NIGHT VISION - 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. | 06-16-2011 |
| 20120019776 | Method for Providing a Spectacle Ophthalmic Lens by Calculating or Selecting a Design - A method for providing a spectacle ophthalmic lens to a wearer, the method comprising the following steps: providing a value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation, according to both visual and non visual frames of reference; calculating a design of the spectacle ophthalmic lens or selecting a design in a spectacle ophthalmic lens design data base by adapting the management of residual astigmatism and/or optical power repartition according to gaze direction based on the value, SV, representing the sensitivity of the wearer referred to a scale of sensitivity to perception of spatial orientation. | 01-26-2012 |
