Abstract

Lente de varias potencias para gafas con al menos dos partes adicionales contiguas entre sí, delimitadas sobre una zona de menor diámetro que la lente principal de una pieza, caracterizada porque las partes adicionales son del mismo material y porque los planos tangentes a las superficies que provocan variaciones del índice de refracción, imaginarios en el centro de las líneas de separación entre las partes adicionales, discurren en cada caso por pares paralelamente.
