Abstract

The invention discloses a preparation method of a full-color-separation color contact lens, which comprises the following steps: 1, stirring a color-changing raw material and a contact lens raw material to form a mixed solution, and then printing the mixed solution on an iris area of a contact lens mold; 2, enabling the mixture for forming the contact lenses to react through a UV illumination program or a heating program to form the contact lenses, and then hydrating; and 3, sequentially soaking the contact lenses in alcohol and water, and finally soaking the contact lenses in a buffer solution for balancing. The manufacturing method has the beneficial effects that the manufacturing method is simple and easy to implement, the full-color-division color contact lens can be manufactured very simply and conveniently, the color patterns are attached to the contact lens, the thickness of the contact lens is very suitable for people to wear, and the wearing comfort of people is improved.

Description

technical field [0001] The invention relates to the technical field of contact lenses, in particular to a method for preparing full-separation color contact lenses. Background technique [0002] Contact lenses, also called contact lenses, are lenses worn on the cornea of ​​the eye to correct vision or protect the eyes. According to the softness and hardness of the material, it includes three types: rigid, semi-rigid, and soft. Contact lenses have brought great improvements to patients with refractive errors such as myopia, hyperopia, and astigmatism not only in terms of appearance and convenience. Moreover, it has a wide field of vision and realistic vision. In addition, it has also played a special role in controlling the development of myopia and astigmatism in young people, and treating special eye diseases. [0003] For friends who wear contact lenses or colored contact lenses for the first time, they will feel uncomfortable. One of the possible reasons is: corneal hyp...
