Abstract: par de lentes oftálmicas progressivas. a presente invenção refere-se a um par de lentes oftálmicas progressivas (1, 2) que encontra condições especiais para aprimorar a visão binocular de um usuário, enquanto evita desconforto para visão periférica. uma primeira dentre as ditas condições relaciona-se com valores de altura de campos de visão afastada, campos de visão intermediária e/ou campos de visão próxima, para indicar que os ditos campos são diferentes o suficiente em termos de altura entre ambas as lentes. uma segunda dentre as ditas condições estabelece um valor máximo para a diferença relativa em gradiente de potência média de refração entre ambas as lentes.

Abstract: A method, implemented by computer means for comparing a first ophthalmic lens with a second ophthalmic lens, the method comprising: - a first optical function providing step, during which a first optical function of a first ophthalmic lens LI is provided, the first optical function comprising at least a first set of values of an optical parameter Gj, the values of the first set of values corresponding to the values of said optical parameter of the first ophthalmic lens in a set of gaze directions, - a second optical function providing step, during which a second optical function of a second ophthalmic lens L2 is provided, the second optical function comprising at least a second set of values of the optical parameter Gj, the values of the second set of values corresponding to the values of said optical parameter of the second ophthalmic lens in the set of gaze directions, - a subsets determining step, during which at least a first and a second subset of gaze directions are selected within the set of gaze directions, each subset of gaze direction comprising at least two gaze directions specific to said subset, - a comparison step, during which for each subset of gaze directions the value of the optical parameter of the first and second optical function are compared using a comparison function associated with said optical parameter, - an assignment step, during which a subset status is assigned to each subset of gaze directions, the subset status being based on the comparison of the value of the comparison function with at least two threshold values T1 and T2 associated with said optical parameter, wherein the subset status is selected among at least three levels.

Abstract: The process comprises: determining prescribed far vision mean power and addition for each lens of the pair; determining laterality of a wearer; defining a temporal side and a nasal side on each lens of the pair; defining on each lens being worn and for each gaze direction a refractive power and a module of resulting astigmatism each gaze direction corresponding to a lowering angle and to an azimuth angle; defining a proximate vision gaze direction for each lens of the pair; defining for each lens of the pair a temporal half width field of refractive power as the angular distance at constant lowering angle between the proximate vision gaze direction and a gaze direction on the temporal side of the lens where the refractive power reaches the value of the prescribed far vision mean power plus three quarters of the prescribed addition; defining for each lens of the pair a nasal half width field of refractive power as the angular distance at constant lowering angle between the proximate vision gaze direction and a gaze direction on the nasal side of the lens where the refractive power reaches the value of the prescribed far vision mean power plus three quarters of the prescribed addition; defining for each lens of the pair a temporal half width field of module of resulting astigmatism as the angular distance at constant lowering angle between the proximate vision gaze direction and a gaze direction on the temporal side of the lens where the module of resulting astigmatism reaches the value of one quarter of the prescribed addition; and defining for each lens of the pair a nasal half width field of module of resulting astigmatism as the angular distance at constant lowering angle between the proximate vision gaze direction and a gaze direction on the nasal side of the lens where the module of resulting astigmatism reaches the value of one quarter of the prescribed addition. The ratio of the difference over the sum of temporal and nasal half width fields of refractive power and/or the ratio of the difference over the sum of temporal and nasal half width fields of module of resulting astigmatism are determined for each lens of the pair based on the laterality of the wearer.
