Publication number: 20220326543Abstract: Method to establish the size of the zones of near Ac, far AL and intermediate Ai vision of a progressive lens by generating, thanks to virtual reality, a gaze map of the user while following a stimulus in at least two planes at two different distances. Once the gaze maps have been made in those two planes or more, the area of each zone is calculated from the maximum horizontal and vertical amplitudes and the points of maximum frequency. In this way, the lens is adapted to the way a user looks.Type: ApplicationFiled: April 6, 2022Publication date: October 13, 2022Inventors: Santiago SOLER MONENTE, Pau ARTÚS COLOMER, Glòria CASANELLAS PEÑALVER, Rocío B.

Patent number: 11156854Abstract: A progressive ophthalmic lens includes at least one multifocal surface, in which at each point of its surface, an astigmatism value and a gradient of astigmatism value can be measured, the lens including: a far-vision zone with a reference point (FV), a near-vision zone with a reference point (NV), an intermediate vision zone with a progression path that connects the far vision zone and the near vision zone, a foveal projection, and a para-foveal projection, and said lens defining a lens addition. When the lens addition is different than 2.00 D, the astigmatism value is k*Add*0.41 D, where Add indicates the lens addition and k is 0.5 and, if the progression path is shorter than 15 mm, the maximum astigmatism value of the foveal projection is (?0.03*d) D/mm+0.86 D, and when the lens progression path is larger than 15 mm, the maximum astigmatism value of the foveal projection is (?0.02*d) D/mm+0.71 D.Type: GrantFiled: August 2, 2019Date of Patent: October 26, 2021Assignee: HORIZONS OPTICAL, S.L.U.Inventors: Pau Artus Colomer, Gloria Casanellas Peñalver, Rafael Perpiñan Blasco

Publication number: 20180196285Abstract: A method for manufacturing an ophthalmic lens including selecting a base of polymeric material and applying a multiple layer structure coating. The coating is selected by designating an interphase, a first layer (of 91-169 nm) with a refraction index higher than 1.8, a second layer (of 128-248 nm) with a refraction index lower than 1.65, a third layer (of 73-159 nm) with a refraction index higher than 1.8 and a fourth layer (of 40-138 nm) with a refraction index lower than 1.8. A total thickness of the multiple layer structure is less than 600 nm. The structure has intermediate layer(s) with intermediate refraction indices, wherein a doublet of two adjacent layers that fulfil the thicknesses above is replaced by a triplet so that the thickness and an optical thickness of the triplet differ from those of the doublet by less than 5%, respectively.Type: ApplicationFiled: March 8, 2018Publication date: July 12, 2018Applicant: HORIZONS OPTICAL S.L.U.Inventors: Franco RIGATO, Glòria CASANELLAS PEÑALVER, Pau ARTÚS COLOMER, Antoni VILAJOANA MAS, Juan Carlos DÜRSTELER LÓPEZ

Patent number: 9459467Abstract: A central area of a lens is defined with a central perimeter coinciding with a perimeter of a frame, a temporal line divides the central area into a nasal area and a temporal area, a useful perimeter is formed from the nasal area and the temporal line, a useful area is delimited by the useful perimeter, and a prescription is determined for the user. The temporal line is outside a cone with at least a 30° opening, an apex of which is in a center of rotation of a user's eye, which is an optical axis. A lens thickness is optimized according to the thickness of the perimeter of the nasal area. Subsequently a transition area is defined extending between the useful perimeter and an external perimeter of the lens.Type: GrantFiled: March 13, 2013Date of Patent: October 4, 2016Assignee: INDO OPTICAL S.L.Inventors: Manel Espínola Estepa, Alberto Lara Rodríguez, Sara Chamadoira Hermida, Glòria Casanellas Peñalver, Pau Artús Colomer, Javier Vegas Caballero
