Abstract

The present invention relates to a colored lens. More specifically, the present invention relates to a colored lens which can achieve various colors by means of a small number of layers by employing asubtractive color mixture printing method. A colored contact lens according to the present invention may comprise: a bottom layer corresponding to a user's eye side; an upper layer opposite to the bottom layer; and a color part placed between the upper layer and the bottom layer, wherein the color part comprises: a base layer formed on the bottom layer and containing an inorganic material; and anorganic color layer formed on the base layer and containing an organic pigment.

Description

technical field [0001] The present invention relates to cosmetic contact lenses. In more detail, it relates to a method of applying subtractive color mixing (Subtractive ColorMixture) printing method, using a small number of layers (Layer) to express a variety of color contact lenses. Background technique [0002] Colored contact lenses (Color Contact Lenses) are contact lenses that can not only correct eyesight but also change the color of the pupils and have a cosmetic effect. [0003] There are roughly two types of contact lenses. [0004] The first is clear contact lenses. [0005] Clear color lenses were developed for the purpose of emphasizing transparency or light blocking effects, rather than changing the iris color. [0006] Conventional clear color lenses use transparent pigments (organic pigments) to express a transparent color, so the color of the user's iris can be seen through the clear color lenses. Therefore, there is a problem that it is difficult to exp...
