Abstract

The invention relates to the technical field of eye care products, in particular to a freeze-dried powder preparation for myopia prevention and eyesight improvement. The freeze-dried powder preparation consists of freeze-dried powder and solvent liquid, wherein raw materials of the freeze-dried powder include (a) an active ingredient, (b) an excipient and (c) an emulsifier; the active ingredient comprises sodium hyaluronate, xanthophyll, ascorbic acid, oligopeptide-1, oligopeptide-5 and pyrimidinecarboxylic acid; the excipient comprises mannitol and sodium chondroitin sulfate; the emulsifier comprises hydrogenated lecithin; and the solvent liquid comprises small molecule alcohol, taurine, betaine, retinol, sodium chloride, lysozyme and deionized water. The freeze-dried powder preparation is prepared by dissolving the freeze-dried powder through the solvent liquid. The invention also provides a preparation method of the freeze-dried powder preparation for myopia prevention and eyesightimprovement. Test results show that the freeze-dried powder preparation can effectively moisturize the eyes, relieve and reduce pressure, resist inflammation, activate the eyes, supplement nutrition and enhance immunity, and has a good nursing effect on myopia prevention and eyesight improvement. And the freeze-dried powder preparation is instantly dissolved and used at one time, is non-irritating, has no toxic and side effects and is very safe to use.

Description

technical field [0001] The invention relates to the technical field of eye care products, in particular to a freeze-dried powder preparation for preventing myopia and improving eyesight and a preparation method thereof. Background technique [0002] According to survey data, the number of myopia in my country is as high as nearly 400 million, of which about 270 million are young people. The incidence of myopia in primary and middle school students is as high as 50%, and the detection rate of related astigmatism, blurring, presbyopia and other poor vision is also increasing, seriously affecting eye health. More than 80% of the onset of myopia is related to acquired factors, including modern increasingly heavy work and study burdens, long-term Internet use instead of movement, bad lifestyles such as using mobile phones, and environmental pollution damage. In terms of scientific mechanism, vision loss such as myopia and astigmatism is also caused by the aging of the body. The...
