Abstract

método para a moldagem por fundição de uma lente de contato. é proporcionada uma lente de contato (60), a qual é produzida por moldagem por fundição. a moldagem por fundição é alcançada por meio do uso de uma inserção de moldagem de face anterior (30), a qual tem uma tampa (24) com uma superfície em domo (26) e um corpo (10). a superfície em domo tem a provisão para um segmento de visão à distância (31) e um segmento de leitura (32), separados por uma demarcação (33). adicionalmente, a tampa (24) tem uma porção de corte (20) para produzir um ressalto inferior e o corpo (10) tem uma projeção (18) para produzir um truncamento inferior na lente resultante. meios também são descritos para a formação de uma face posterior da lente de contato (60).
