Embodiment 1

[0040] The preparation of embodiment 1 composite structural color contact lens

[0041] Such as figure 1 and figure 2As shown, the composite structural color contact lens includes a contact lens body 1, and the outside of the contact lens body 1 is uniformly solidified with a structural color colloidal crystal solution polymer of a single color or a mixed color as a structural color region. The structural color area includes the pupil area 11 and the iris area 12 formed by the outward protrusion of the contact lens body 1; the pupil area 11 is a colorless and transparent area; the iris area 12 is a uniform single color or mixed color structure Structural colored regions formed by solidification of chromatic colloidal crystal solution polymers. The structural color colloidal crystal polymer solution is methyl methacrylate, polyhydroxyethyl methacrylate, cellulose acetate butyrate, siloxane methacrylate, fluorosilicon methacrylate, perfluoroether, N - Any mixture of one or m...

Embodiment 2

[0051] The preparation of embodiment 2 composite structural colored contact lenses

[0052] The raw material formula is as follows:

[0053]

[0054] 1. Preparation of structural color colloid solution:

[0055] Configure two kinds of structural color colloidal solutions, and add monodisperse colloidal silica nanoparticles with a diameter of 200 nanometers into a mixed solution of hydroxyethyl methacrylate (HEMA) and ethylene glycol dimethacrylate (EGDMA), adjust The mass percent of silicon dioxide is 40% and 60%, ultrasonic dispersion, all produces bright and bright structural color until two kinds of colloidal particle solutions; In this solution, add initiator azoisodibutylcyanide (0.1%, mass volume ratio), after fully mixing, pass through nitrogen gas for 5 minutes, and seal the structural color colloid solution for later use.

[0056] 2. Curing treatment of structural color solution in the mold:

[0057] Firstly, a 100 microliter volume of structural color colloid s...

Embodiment 3

[0060] The preparation of embodiment 3 composite structural colored contact lenses

[0061] The raw material formula is as follows:

[0062]

[0063] 1. Preparation of structural color colloid solution:

[0064] Configure two kinds of structural color colloidal solutions, and add monodisperse silica colloidal nanoparticles with a diameter of 200 nanometers into a mixed solution of siloxane methacrylate (SMA) and ethylene glycol dimethacrylate (EGDMA), Regulate the mass percent of silicon dioxide to be 40% and 60% respectively, and ultrasonically disperse until the two colloidal particle solutions all produce bright and bright structural colors; add initiator azoisodibutylcyanide (0.1%, Mass to volume ratio), after fully mixing, pass through nitrogen gas for 5 minutes, and seal the structural color colloid solution for later use.

[0065] 2. Curing treatment of structural color solution in the mold:

[0066] Firstly, a 100 microliter volume of structural color colloid sol...

Abstract

The invention discloses a composite structured colored contact lens which comprises a contact lens body (1); and the composite structured colored contact lens is characterized in that a uniform single-colored or mixed-colored structural colour colloidal crystal solution polymer serving as a structural colour area is cured at the outside of the contact lens body (1). Compared with other contact lenses, the composite structured colored contact lens disclosed by the invention is more beautiful, good in biocompatibility and good in practicability.

Description

technical field [0001] The invention belongs to the technical field of contact lens material research, in particular to a compound structural colored contact lens. Background technique [0002] In the past 30 years, the total number of people wearing contact lenses in the world has increased by 35 times, and colored contact lenses have gradually become popular due to the drive of the global fashion industry. According to incomplete statistics, my country's colored contact lenses currently account for more than 35% of the contact lens market. [0003] Colored contact lenses can be divided into two categories: the first category is a contact lens with transparent or opaque colored patterns only in the iris area of ​​the contact lens, which can reveal special colors and patterns in the iris area of ​​the contact lens; the second category Colored contact lenses use transparent colors to enhance the color of contact lenses. This basically transparent coloring material is evenly ...
