Problems solved by technology

[0006] The existing common methods for treating eye diseases such as myopia and cataract include drug therapy and surgical treatment. Among them, surgical treatment has damage to the human body or has sequelae, and there is still a certain risk. However, the current drug treatment mostly uses eye drops or eye ointment. But the effect is not obvious, and the production process is complicated, it is difficult to eliminate a large number of free radicals in the eyeball and surrounding microvessels and nerves
[0007] At the same time, in order to eliminate a large number of free radicals produced by excessive eye use and environmental factors, according to relevant records, eating blueberries, black wolfberry, mulberry, vitamin E, vitamin C or selenium-containing high-efficiency substances to fight free radicals, etc., has a good effect on myopia and cataract. have some effect, but the effect is not obvious

Abstract

The invention relates to eye drops for treating myopia and cataract and a preparation method thereof. The eye drops for treating myopia and cataract are prepared from nanogold and deionized water, theparticle size of the nanogold is 1-100 nm, and the concentration of the nanogold in the eye drops is 0.01-100 ppm; and the preparation method comprises the steps of adding a nano-gold solution with the concentration of 50-60 ppm into 60-100 times of deionized water, and uniformly stirring the solution to obtain the nano-gold eye drops. The nanogold (nonionic) outer layer has high electron cloud density and catalytic action, can be combined with various biomacromolecules, does not affect the biological activity of the biomacromolecules, and effectively neutralizes and eliminates free radicalsat eyeball parts under the action of deionized water, so that an obvious treatment effect on eye diseases such as myopia and cataract is achieved.

Description

technical field [0001] The invention relates to an eye drop, in particular to an eye drop for treating eye diseases such as myopia and cataract and a preparation method thereof. Background technique [0002] With the different living habits and environments of modern people, such as long-term use of mobile phones, reading books, or other excessive use of the eyes, and more importantly, the long-term lack of living environment with negative ions, the ciliary body, lens, eyeball and surrounding areas of the eye will be damaged. Capillaries and nerves are prone to a large number of enrichment of free radicals, resulting in eye diseases such as myopia or cataracts. [0003] According to relevant literature, it is found that myopia and cataracts in the agricultural era are significantly less than those in the existing industrial era, especially now that industry and information technology are inseparable from mobile phones and computers. This is the root cause of modern people's ...
