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.
