preparation example Construction

[0018] The preparation method of the described ophthalmic lens of one embodiment of the present invention comprises the following steps:

[0019] Mixing the hydrogel precursor or the silicon hydrogel precursor and the eyebright extract evenly according to a preset ratio to obtain a mixed solution;

[0020] Provide an ophthalmic lens mold, and place the above mixed solution in the ophthalmic lens mold;

[0021] UV light irradiates the mixed solution in the mold of the ophthalmic lens, so that the hydrogel precursor or the silicone hydrogel precursor undergoes a copolymerization reaction to form a matrix, and the eyebright extract is mixed in the matrix to obtain a product containing Ophthalmic lenses with eyebright extract.

[0022] The preparation method of the ophthalmic lens of another embodiment of the present invention comprises the following steps:

[0023] Provide an ophthalmic lens mold, place the hydrogel precursor or silicone hydrogel precursor in the ophthalmic len...

Embodiment 1

[0028] In the ophthalmic lens, the mass percentage of the matrix is ​​98.5%, and the mass percentage of the eyebright extract is 1.5%.

[0029] The matrix is ​​a hydrogel matrix, mix 64mg hydroxyethyl methacrylate, 3mg ethylene glycol dimethacrylate, 0.05mg Irgacure-1173 and 1mg eyebright extract, and then put the mixed solution on the ophthalmic lens The mold is irradiated with UV light for 30 minutes to prepare ophthalmic lenses containing the eyebright extract.

Embodiment 2

[0031] In the ophthalmic lens, the mass percentage of the matrix is ​​99.5%, and the mass percentage of the eyebright extract is 0.5%.

[0032] The matrix is ​​a hydrogel matrix, and the ophthalmic lens is uniformly mixed with 64mg hydroxyethyl methacrylate, 3mg ethylene glycol dimethacrylate and 0.05mg Irgacure-1173, and then the mixed solution is placed on the ophthalmic lens In the mold, after irradiating with UV light for 30 minutes, a lens that does not contain eyebright is prepared, and then the ophthalmic lens that does not contain eyebright is immersed in eyebright with a mass concentration of 10 mg / mL produced by Xi'an Dien Bioengineering Co., Ltd. After being in the solution for a period of time, the ophthalmic lens containing the eyebright extract is obtained.

[0033] The ophthalmic lens of the present invention contains eyebright extract, which can be slowly released from the ophthalmic lens to treat eye inflammation (such as conjunctivitis, blepharitis, stye), ey...

Abstract

The invention relates to an ophthalmic lens, which comprises a matrix and a Euphrasia pectinata extract dispersed in the matrix. The ophthalmic lens contains the Euphrasia pectinata extract, which can be slowly released from the ophthalmic lens to treat eye inflammation (like conjunctivitis, blepharitis, hordeola), eye bleeding, eyestrain and other symptoms. The released Euphrasia pectinata extract also has the effects of disinfection, antioxidation, eyesight improving, eye function improving, pouch eliminating, and black eye elimination, etc. In addition, the invention also provides a preparation method of the ophthalmic lens.

Description

technical field [0001] The invention relates to an ophthalmic lens and a preparation method thereof. Background technique [0002] In recent years, with the increasing number of myopic people, contact lenses have been widely used because of their portability and aesthetic characteristics. In addition, for people with high myopia, the transparent lens (lens) is generally removed, and then an intraocular lens (artificial lens, etc.) is implanted, so that the person with high myopia can see objects clearly. Prolonged use of ophthalmic lenses such as contact lenses and intraocular lenses can easily cause eye inflammation and other symptoms. However, the main purpose of current ophthalmic lenses is to enable users to see objects clearly, and they do not have the effect of preventing and treating symptoms such as eye inflammation, eye bleeding, and eye fatigue. Contents of the invention [0003] In view of this, it is necessary to provide an ophthalmic lens for treating and pr...
