Problems solved by technology

When considering the shape, it is usually necessary to consider its oxygen permeability, permeability and other issues. Therefore, it does not mean that the expected goal can be achieved after a well-designed shape. Sometimes, after the design is completed, only through wearing it in a real environment, Considering the iris conditions of various wearers, it is very difficult to determine whether the design is successful after repeated experiments

Embodiment Construction

[0014] The present invention provides a kind of color contact lens, which has a transparent central optical zone, a transition zone and a colored zone located on the periphery. It is characterized in that the central optical zone provides an optical viewing zone, and the transition zone is the optical zone and The colored area provides a transitional area, the colored area is an opaque area, and provides a colored area for the contact lens, and the colored area is formed to be composed of individual honeycomb-shaped microstructures, and the size of the honeycomb-shaped microstructures gradually decreases , the chromaticity gradually weakens, and it is basically transparent near the transition zone, wherein there are gaps between the honeycomb-shaped microstructures, the diameter of the central optical zone is 8-10mm, and the diameter of the transition zone is about 1-2mm , the diameter of the colored area is about 13 mm, the honeycomb-shaped microstructure has a size of 300-500...

Abstract

The invention provides a colorful contact lens which can supply the more natural appearance to the pupil of a contact lens wearer and enable the color of the pupil to present the different textures under the different scenes according to the irises of the different wearers. The colorful contact lens is provided with a transparent central optical zone, a transition zone and a coloring zone located at the periphery of the lens, wherein the coloring zone serves as a zone which is non-transparent, supplies colors to the contact lens and is composed of multiple honeycomb-shaped microstructures.

Description

technical field [0001] The invention relates to a cosmetic contact lens. Background technique [0002] The market share of contact lenses is increasing. With the improvement of people's living standards, contact lenses are not only used for vision correction, but also endowed with the effect of a color contact lens, and are more and more favored by beauty lovers. [0003] As a method of coloring contact lenses, the method of applying dyes or printing and coloring the inner and outer surfaces of the lenses is usually used, and most of the current popular cosmetic contact lenses use the latter method. Such as coating the color monomer component on the surface of the lens forming mold to form the iris part, after film formation, polymerize the monomer component for filling the lens, and then take it out of the mold, thereby forming a coloring with the effect of cosmetic contact lenses The method of contact lenses; also such as contact lenses in which the colored part is embedd...
