Abstract

"PAR DE LENTES CORRETIVAS PROGRESSIVASMULTIFOCAIS". Onde cada lente tem uma superfície não esféricacom uma zona de visão de longe, uma zona de visão intermediáriae uma zona de visão de perto e uma boa visão foveal monocular ebinocular ao longo do meridiano principal. Em cada ponto dasuperfície não esférica, há uma esfera média que é proporcional àmeia soma dos raios máximos e mínimos da curvatura expressosem metros, e ao índice de refração do material da lente. Ainvenção sugere a redução, para uma determinada direção devisão, do valor absoluto da diferença entre um parâmetro dabinocularidade para dois pontos no espaço do objeto. O parâmetroda binocularidade é definido para um ponto no espaço do objetocomo a diferença relativa <30>S da esfera média para os pontosda superfície não esférica das lentes direita e esquerda atravésdas quais o usuário vê o dito ponto."PAIR OF PROGRESSIVE MULTIFOCAL CORRECTIVE LENSES". Where each lens has a non-spherical surface with a long-range vision zone, an intermediate-vision zone and a near-vision zone, and good monocular and binocular foveal vision along the main meridian. At each point on the non-spherical surface, there is an average sphere that is proportional to the half sum of the maximum and minimum radii of curvature expressed in meters, and the refractive index of the lens material. The invention suggests the reduction, for a given direction of vision, of the absolute value of the difference between a binocularity parameter for two points in the object's space. The binocularity parameter is defined for a point in the object space as the relative difference <30> S from the middle sphere to the points on the non-spherical surface of the right and left lenses through which the user sees said point.
