Abstract

abstract this invention provides for the fabrication of ophthalmic lenses via the utilization of dmd shows and/or dmd files. more specifically, the use of the dmd shows and/or dmd files to generate lens precursor designs comprising described features to form part of a substructure for the fluid reactive media portion of the lens precursor and wherein the lens precursor can generate particular ophthalmic lens designs in a free-form manner using methods described herein. ********************** tradução do resumo resumo patente de invenção: "precursor de lente com características para a fabricação de uma lente oftálmica". é apresentado um método para desenhar uma forma precursora de lente (105b) que compreende definir o desenho de uma forma precursora de lente, sendo que o desenho inclui uma borda da lente (hob) que define o perímetro externo da forma precursora de lente; uma pluralidade de características da lente, selecionadas do grupo consistindo em uma característica de borda da lente que está presente ao longo de pelo menos parte da borda da lente, uma zona óptica (125b) que está presente no interior do perímetro externo da forma precursora de lente, uma característica de zona de estabilização (115b) que está presente no interior do perímetro externo da forma precursora de lente, e uma característica de avolumador (120b) que está presente no interior do perímetro externo da forma precursora de lente entre pelo menos duas da dita pluralidade de características da lente; sendo que cada uma das características da lente é parametricamente definida, e sendo que os parâmetros que definem pelo menos uma característica de lente são selecionados com base, pelo menos em parte, nos parâmetros que definem uma ou mais características de lente adjacentes e um formato de lente desejado. 23451456v1 1/1 23451456v1
