Abstract

elemento óptico semiacabado para fabricação de um artigo oftálmico, artigo oftálmico e método de fabricação relacionado. a presente invenção refere-se a um elemento óptico semiacabado (sf) para fabricação de um artigo oftálmico (1) para correção de visão compreendendo: - pelo menos um bloco bruto (3) tendo uma dioptria frontal (3f) e uma dioptria traseira (3r), sendo o bloco bruto (3) configurado para apresentar uma primeira distribuição de potência óptica, - estando uma das dioptrias (3f, 3r) inacabada e estando a outra acabada, - uma camada de componente óptico (5) compreendendo uma disposição periódica ou pseudoperiódica de elementos de formação de frente de onda ópticos (5e) que são menores que 10 µm e configurados para controlar luz recebida pelo menos em uma parte do espectro visível e fornecendo uma segunda distribuição de potência óptica, em que a camada de componente óptico (5) é transparente em transmissão no comprimento de onda visível e está disposta na dioptria acabada (3f, 3r) do bloco bruto (3) para cooperar em conjunto para alcançar uma terceira distribuição de potência óptica.
