Abstract

PRÉ-CURA COM MÁSCARA DE LENTES DE CONTATO: SISTEMAS E MÉTODOS DA MESMA. A presente invenção refere-se a métodos e sistemas para fabricação de lentes de contato coloridas. São descritos conjuntos de molde da lente de contato que incluem metades de molde da lente de contato, pelo menos uma das quais inclui uma substância corante. Uma porção do material de formação de lente curável é pré-curada, enquanto uma porção do material de formação de lente curável em contato com a camada de cor permanece substancialmente não curada para permitir a difusão da substância corante para as lentes.
