Therefore, the use of transparent tinted contact lenses to change the eyeballs to the desired color is limited to a certain extent, and its main use is not beauty but recognition or ultraviolet shielding, etc.
[0008] The second type is non-transparent tinted contact lenses that can change the original iris color to other colors, but the non-transparent pigments used in such contact lenses are usually larger in particle size than the pores of soft contact lenses, making it difficult to remove the pigments. Tint directly onto contact lenses
Moreover, the iris texture printing of the colored soft contact lens is complicated and difficult, which increases the production cost

The present invention relates to a colored hard contact lens printing method for printing an iris design on the whole surface of a hard contact lens, the method comprising: a preparation step of preparing a hard contact lens, a centering jig, and a composition for printing so as to print an iris design on the hard contact lens; a printing step of mounting the hard contact lens on the centering jigand printing the iris design by using the composition for printing; and a post-treatment step of post-treating the hard contact lens having the iris design printed thereon. Therefore, the present invention prints iris designs of various colors and patterns on the outer circumference of the front surface of the hard contact lens by using the composition for printing, thereby providing an effect ofmanufacturing a colored hard contact lens having iris designs of various colors and patterns on the front surface thereof.
Description
technical field [0001] The present invention relates to a printing method of a colored hard contact lens. More specifically, the present invention relates to a colored hard contact lens that prints iris textures with diverse colors and patterns on the outer edge of the front surface of the hard contact lens printing method. Background technique [0002] People with weak eyesight or problems with astigmatism often wear glasses or contact lenses. Although wearing contact lenses is inconvenient, they are favored by many because they are invisible from the outside. [0003] Contact lenses are classified according to the material of the lens as follows: soft contact lenses, which are made of soft materials, mainly disposable or regular replacement soft contact lenses that can be used for a short or long time; hard contact lenses, which are made of hard materials Composition, can be used for a long time or for a long time. [0004] People have successfully developed contact lens...
