preparation example Construction

[0049] The preparation raw material of the reflective layer is photochromic ink.

[0050] In the present invention, taking the center of the spherical surface as the center, the distribution density of the convex dots preferably increases in the direction of outward extension; the increasing trend is preferably a regular increase or an irregular increase; The law of the regular increase is not limited in any way. In the present invention, the size of each of the raised dots is preferably the same or different.

[0051] In the present invention, the diameter of the raised dots is preferably 0.02 to 1.5 mm, more preferably 0.08 to 1.0 mm, and most preferably 0.2 to 0.6 mm; the angle between two adjacent raised dots is preferably 30° to 180° °, more preferably 40°-130°, most preferably 60°-100°; the height of the raised dots is preferably 8-22 μm, more preferably 10-20 μm, and most preferably 13-16 μm. In the present invention, the raised dots preferably have a "U"-shaped struc...

Embodiment 1

[0092] Using laser engraving method, the steel plate is laser engraved to obtain the pattern mold of Guangyao 5D colorful color contact lens, and then the carrier plastic mold of Guangyao 5D colorful color contact lens is obtained through color contact printing technology; the shape of the carrier plastic mold is similar to the eyeball surface. match, the carrier plastic mold is centered on the center of the spherical surface, along the line of defense extending outward, including a central spherical area, an annular spherical area and an edge spherical area; the surface of the annular spherical area is provided with concave mesh points ( The structure of the concave mesh point is as follows image 3 As shown in the figure, the diameter of the dots is [0.02mm~1.5mm], and the layout gradually increases in the form of dots, and the connection layout between dots presents various angles [30°~180°]. The purpose of designing the distribution of dots of different sizes : make differ...

Abstract

The invention relates to the technical field of cosmetic contact lenses, in particular to a blazed 5D colorful cosmetic contact lens and a preparation method thereof. The invention provides a blazed 5D colorful cosmetic contact lens. The blazed 5D colorful cosmetic contact lens comprises a cosmetic contact lens body matched with the curved surface of an eyeball. The cosmetic contact lens body takes the center of the spherical surface as the center, and comprises a central spherical surface area, an annular spherical surface area and an edge spherical surface area along the outward extending direction; the inner and outer curved surfaces of the cosmetic contact lens body are smooth; the cosmetic contact lens body sequentially comprises a first semi-absorption layer, a first thin film layer, a reflecting layer, a second thin film layer and a second semi-absorption layer from inside to outside in the thickness direction; the surface, corresponding to the reflecting layer, of the annular spherical area is provided with protruding net points, and the protruding net points are embedded and inserted into the second thin film layer; the thickness of the second thin film layer is greater than or equal to the height of the convex lattice points; and the preparation raw material of the reflecting layer is photochromic ink. The blazed 5D colorful cosmetic contact lens can present different color changes along with different viewing angles.

Description

technical field [0001] The invention relates to the technical field of color contact lenses, in particular to a bright 5D colorful color contact lens and a preparation method thereof. Background technique [0002] Cosmetic contact lenses are usually painted with fuel or printed on the inner and outer surfaces of the lenses to make the contact lenses have the effect of coloring. In most of the current solutions, a coloring area is set outside the central optical area, and the coloring area is designed to be various colors that imitate the natural pupil. However, the color is single and lacks the effect of transparency and metallic flickering. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a brilliant 5D colorful contact lens and a preparation method thereof, the brilliant 5D colorful contact lens can show different color changes with different viewing angles. [0004] In order to achieve the above-mentioned purpose of the invention, t...
