Abstract

Patente de Invenção: <B>"óTICO INCORPORANDO UMA VARIAçãO DE GRAU"<D>. é proporcionado um ótico progressivo (10) dotado de uma preforma ótica (30) onde o raio de curvatura da superfície é alterado ao se formar porções esféricas discretas (20) através da superfície. Uma camada intermediária delgada (40) tendo um índice refrativo diferente a partir da preforma ótica (30), é então fundida sobre a superfície de preforma ótica formada. A preforma ótica (30) tendo uma camada intermediária delgada (40) é então fundida com uma camada de superestrato de resina (60) que restabelece a curvatura do ótico (10). Cada seção esférica (50), definida pelas porções esféricas (20) e pelas porções correspondentes da superfície externa da camada de superestrato (60), altera o grau esférico da seção esférica adjacente (50) em cerca de0,03D a 0,05D.
